DSH
  1045 05/27/09 VA P 1 Correct OPEN and CLOSE macros to only assume register notation for DCB if in (...) as 0 is often used as place holder for MF=L. Require ((reg)) for single DCB register notation per macros for data sets manual.  See correction to rt\test\TESTDCBF.MLC. DSH
  1046 05/28/09 VA P 1 Reset RLD count after each NAME command in LKD to prevent erroneous RLD's added to each following load module.  Correct TRACEL display of AL3 field values (shift right 8). DSH
  1047 05/28/09 VA P 2 Correct az390 to issue AZ390 ENDED message versus MZ390 when running separately from MZ390.  AK
  1048 06/02/09 VA P 1 Correct zcobol to prevent erroneous working storage length errors when files are defined.  See change to zcobol\WORKING_STORAGE.MAC, zcobol\z390\GEN_WS.MAC, and regression tests zcobol\test\TESTFIL1 and 2. HD

  1053 06/07/09 VA P 1 Changes and corrections for AINSERT processing:
1)  Change z390 options processing to check option NOASM for required CHKMAC(0) and CHKSRC(0-2).  This will allow NOASM to load data inline via COPY or AINSERT without checking it for content. 2)  Add AINSERT record trace for TRACEM, and prevent trap on negative file index when loading macros and copybooks from AINSERT records. 
3)  Require explicit FRONT or BACK on each AINSERT.
4)  Correct AINSERT of COPY at FRONT to load in sequential order instead of reverse order.
See new rt\test\TESTERRA.MLC ASM regression test for invalid ASCII and missing label warnings moved from TESTERR1 which uses NOASM.

4)  Correct prefix on SYSTERM ERR file listing for MNOTE's listed by az390 during last pass.
5)  Convert MNOTE text to printable ASCII with periods for non-printable characters such as (x'00'-x'1f') and (x'80'-x'ff').
See correction in rt\test\TESTOPR1.MLC, rt\test\TESTMAC1.MLC, rt\test\TESTSET1.MLC, and added error message testing in rt\test\TESTERR1.MLC.
AK
  939 10/29/08 VA P 1 Correct DC Z'nnn' to pad field with 0's on the left instead of right.  It didn't get done in RPI 930 for v1403c as intended. DSH
  940 10/30/08 VA P 1 Correct TN3270 SBA calculation for field defined at (24,80) which returned SBA x'115E40' instead of x'114040'. MM
  941 10/31/08 VA P 1 Correct z390 assembler to start CNOP on next half-word aligned byte forcing any label on half word boundary per HLASM docs.   See change in rt\test\TESTINS2.MLC PRN listing showing corrected address for REGS label following CNOP at odd address. MW
  942 10/31/08 VA E 1 Change CALL macro to issue error if (1) register is specified as parm which destroys the parameter block pointer. HLASM docs say only 2-12 can be specified in register notation.  Change RETURN, RESTORE, and ZOPTLR macros to correctly support RC=(15). MW
  943 10/31/08 VA P 1 Change z390 macro assembler to insert absolute value of SETA variables in SETC expressions and model statements.  Use the prefix operator A2D or SIGNED to return SETC string with negative sign if required (A2D also returns plus sign.  See rt\test\TESTSDT1.MLC and  rt\test\TESTOPR1.MLC for regression test examples. MW/RB

  945 11/03/08 VA P 1 Correct mz390 error processing when ERRSUM is on, to force all error messages to BAL output as comments since this is the only record of any macro processing errors encountered.  Only missing macro and copybooks are listed on console and ERR file for ERRSUM processing along with detail mz390 and az390 error counts..  See the PRN listing for any processing errors which could affect which if any missing macros and copybooks are found. AK
  946 11/05/08 VA E 1 Change lz390 linker to set all uninitialized areas of load module to X'F6' instead of X'00' when option INIT is on (the default).  Use NOINIT to revert to all x'00'.  Uninitialized areas of load module include areas defined via DS or ORG to higher relative address.  In order to run with default INIT, the following z390 changes have been included:
1)  mac\DCB initialized to zeros before ORG's to fields.
2)  vse\mac\DTFPR and DTFCD initialized to zeros
3)  mac\CASENTRY and CASE initialized address table to 0
4)  mfacc\P11DSH1.MLC and P11DSH2.MLC initialize hash table to 0

  929 10/06/08 VA P 1 If generated label field starts with * or .* force comment.  This is intentionally different from HLASM which processes statement as a macro call if the first space delimited word in statement with generated label field happens to be a defined macro or opcode.  A request has been submitted to IBM to also change HLASM behavior.  See updated regression test rt\test\TESTASM1.MLC DW
  930 10/08/08 VA P 1 Misc. corrections:
1) Reset mz390 SPE level and AENTRY name table at start of every macro load.
2) Correct az390 DC Z type field support to prevent trap on invalid alphabetic characters in field.
3) Allow (..) type comments on AIF type ZSTRMAC statements
4) Correct DC Z'nnn' to put F0 in leading zero bytes.
5) Add macro variable compare and store value display to TRACEM.
6) Add global setc macro variable &SYSTRACE which can be used to set to 'M' for TRACEM, 'P' for TRACEP, "C" for TRACEC, or '*' for TRACEALL, or '' to turn off all trace options dynamically after tracing selected section of macro code during macro execution.
DSH
  933 10/21/08 VA P 2 Correct MNOTE warning for statement following MEND to report error on the macro being loaded rather than the calling macro. AK

AK
  797 01/24/08 VA E 1 Change RTLIST regression test process to remove all DIF files with no changes plus the RTGEN utility files.  These three conditional macro code utilities have been updated to use ZSTRMAC extensions to simplify this update and make the programs easier to maintain:
1)  linklib\RTGENDIR.MLC - read directory listing and create file with just file names.
2)  linklib\RTGENCMP.MLC - read sorted file names from 2 directories to be compares and generate BAT file with FC compare commands for matching files and PAUSE errors for unmatched files.
3) linklib\RTGENDIF.MLC - read file names in DIF directory, open file and check for no differences message and gen BAT file with erase commands for matching files.  Create empty text file at end with name "RT_DIF_TOT_FILES_NNNN" and "RT_DIF_TOT_MATCH_NNNNN" showing the total number of DIF files found and the total number of identical matching file DIF's removed.

In addition, the option NOTIMING has been changed to surpress the z390 and J2SE versions from step started messages and remove the total memory used from step ended messages to reduce the number of DIF files showing differences.
AK
  902 09/01/08 VA E 1 Integrate ZSTRMAC Structured Conditional Macro Code Extentions into mz390 macro processor during loading of source code to eliminate need for separate translation.  The following programs have been updated and tested using mz390 integrated support of ZSTRMAC structured conditional macro code:

  894 08/11/08 VA P 1 Correct new support for AL2 relocatible expressions to generated 2 byte RLD.  Change start of CVT TO x'2000' and start of DSA to x'8000' to allow testing new regression test rt\test\TESTRLD2 using AL2 RLD with option NOLOADHIGH below 64k limit.  Issue linker and loader errors when AL2 and AL3 RLD field offsets or addresses exceed field limit. DSH
  895 08/11/08 VA E 1 Change ERRSUM option processing to always generate PRN using ERR(0) to prevent abort prior to identifying all macro and copybook references.  To suppress the PRN listing when using ERRSUM and ERR(0), add option NOLIST.   Change MNOTE with error level to increment the associated file error count. AK
  896 08/12/08 VA E 1 Add z390 ZSTRMAC Structured Macro Assembler Support extensions:
1. AIF (condition)- start of conditional block of macro code
2. AELSE - start of alternate block of macro code within AIF
3. AELSEIF - start of alternate AIF or ASELECT block
4. AEND - end of AIF, APM, AWHILE, AUNTIL, and ASELECT.
5. APM name - perform block of macro code starting at label
6. AENTRY name entry point for performed block of macro code.  AENTRY/AEND blocks are skipped during fall thru execution.
7. AEXIT type - exit from APM, AWHILE, AUNTIL, or ASELECT structure at corresponding AEND.  Note AEXIT skips AIF levels..
8. AWHILE (condition) start repetition block of macro code with test at start
9. AUNTIL (condition) - start repetition block of macro code with test at end
10. ASELECT (expression) - select case based on expression value
11. AWHEN (value 0 - 255) - start block of code for select values. Values can be decimal, C'?', X'??', or range in the form (v1,v2) separated by commas.
12. To allow indenting instructions with label fields, any statement starting with : will have text following : placed in label field.

These extensions are only allowed if ALLOW option is on.  A optional separate utility linklib\ZSTRMAC.MLC and command ZSTRMAC.BAT are included to convert macro source file to standard HLASM form for portability.  Regression tests include:
1) rt\test\ZSTRMAC1.MLC - bootstrap translator in HLASM form.
2) rt\test\ZSTRMAC2.ZSM - structured translator using its own structures.  Both ZSTRMAC1.MLC and the generated ZSTRMAC2.MLC both generate identical copy of ZSTRMAC2.MLC.  However note ZSTRMAC2 supports AWHEN extended forms not supported by ZSTRMAC1.MLC.
3) rt\test\TESTZSM1.ZSM - test basic structures using strmac1
4) rt\test\TESTZSM2.ZSM - test basic structures using strmac2

  883 07/27/08 VA E 1 Add option MOD to generate raw code file from lz390 with suffix .MOD and no header or trailer, no rounding to multiple of 8, and no RLD's.  For example source DC C'ABC' with option MOD will create MOD file with 3 hex bytes x'C1C2C3'.  This type file can be loaded as data table by Micro Focus CICS. DSH
  884 07/30/08 VA E 1 Add ASMMREL macro with positional operand ON or OFF.  If ON is specified OPSYN commands are issued to substitute branch relative instructions in place of branch displacement opcodes, and long displacement opcodes are substituted for equivalent standard base displacement opcodes to help reduce base register requirements.  Beware that any relative instruction branching using *+- may require change due to instruction length changes from 4 to 6 bytes.  DSH
  885 07/30/08 VA E 1 Add SYSSTATE macro with default AMODE64=NO,ASCENV=P,ARCHLVL=2.  Issue warning if AMODE64=YES, ASCENV=AR, or ARCHLVL > 2 since these modes are not currently supported in z390. DSH

MS/NTK
  814 02/27/08 VA P 1 Change lz390 linker to search linklib directory for unresolved external references if autolink is on and no explicit SYSOBJ directory has been specified.  Add missing z10 DFP instruction SQXTR using macro and statically linked CSECT (this is z390 equivalent of millicode for testing new instructions).  Since there is still no support for SQXTR DFP square root instruction corresponding to SQXR HFP and SQXBR BFP instructions, the mac\SQXTR.MAC,  linklib\SQXTR.MLC, and linklib]SQXTR.OBJ files have been added to support SQXTR as extended z390 instruction.  The code originally published in ZMFACC contest problem #12 to calculate standard deviation has also been improved to optimize first quess per Martin Wards suggested reference by reducing exponent by half for first guess.  Tests show SQXTR for value 1E4 and 1E-4 only require 1 iteration to find 1E2 and 1E-2 solutions but SQRT(3.5) still requires 7 so there is room for further improvement on first guess. DSH
  815 02/26/08 VA P 1 Correct pz390 execution hyper bug in all indexed instructions preventing negative index register value from working correctly.  See updated rt\test\TESTINS2.MLC to test IC instruction with index register value of -1 to fetch byte from base + displacement - 1. BL

2)  Correct DFP support to honor add, subtract, divide, and multiply IEEE exceptions for divide, overflow, and underflow based on FPC register.
3)  Correct HFP to support un-normalized input constants which were being incorrectly converted when more there were more than  3 leading zero bits in mantissa.  See RPI 821 for pending fix for low nibble error in HFP DH calculations.
4)  Correct floating point caching to allow reuse of second floating point register in a pair without storing the previous pair which flushes extended value for the pair.

  782 01/08/08 VA P 1 Stop the interval timer process at exit from ez390 to prevent occasional thread exceptions during shutdown of ez390. DSH
  786

 

01/11/08 VA P 1 Change az390 to generate decimal floating point constants with preferred exponent of -2 if possible without loss of significance.  Previously DFP constants were generated with smallest quantum which is arithmetically equivalent.  See IBM Journal reference article.  See updated regression tests linklib\TESTFP1.MLC, rt\test\TESTDFP1.MLC, and rt\test\TESTCFD1.MLC which have been changed to use arithmetic compares versus CLC compares to allow for constants and calculated results to compare equal even thought they have different canonical forms.  The lastest POP describes the preferred canonical forms for different DFP operations in table 20-4. BL
  787 01/13/08 VA P 1 Correct support for DFP un-normalized instructions:
1) Flush cached un-ormalized result to register for following store.

  746 12/01/07 VA E 1 Move generated BAL comment for macro calls before initial load to more easily identify source of any macro loading errors or missing macro label warnings.  Also correct  source file cross reference line number reference errors in TRM trace file for TRACEM. AK
  747 12/01/07 VA E 1 add options to control level of z390 checking in RPI 747 as follows:
CHKSRC(n) where n is as follows with default CHKSRC(1):
0 - no checking for ASCII (allows non-printable ASCII characters in source which may or may not result in errors later in assembly or execution depending on whether they appear in comments or in character strings intended to be hex EBCDIC characters. These need to be in X'...' format for portability.
1 - check for any non-printable ASCII characters in MLC source.
2 - check for any non-printable ASCII characters in all MLC and macro source code.  Note COPY sources are always checked along with files that include them.

CHKMAC(n) where n is as follows with default CHKMAC(0):
0 - no checking for missing macro labels and no checking for source statements after final MEND.
1 - check for missing macro labels during loading and generate warnings.
2 - check for missing labels and check for any source statements after final MEND and generate warning.

Misc related fixes:
1.  Correct line number reference for bad character error messages.
2,  Correct az390 to generate private CSECT for any opcode prior to first section declaration.
See usage on rt\test\TESTERR1.MLC.
AK
  749 12/02/07 VA E 1 Misc. fixes for az390 assembler:
1) Issue error for EQU expression referencing itself (X EQU X).
2) Issue error for literal with forward referenced symbols in modifiers such as =C(SECTLEN)' '.  Alternate code paths could change value of lookahead symbol resulting in erroneous literal.  Note HLASM does not perform lookahead for literal references whereas z390 always does lookahead for entire source file during loading into memory prior to pseudo code generation.  See updated rt\test\TESTERR2.MLC
r
  750 12/03/07 VA P 1 Corrections and enhancements to VSAM KSDS support:
1) Trace RPL after each function for TRACE(V)

  742 11/17/07 VA E 1 1) Issue error message and abort if option is not recognized.
2) Add @filename option to include options from free form text file with optional comments starting with *.  Default file name suffix is OPT, and search path is SYSOPT which defaults to program directory.  SYSCPY changed to default to SYSMAC which defaults to program directory.  Any number of @files can be specified and they can be nested.  See rt\test\TESTOPT1 regression test.
3) If any option with directories or files is specified and it starts with +, then concatenate with any prior setting for that option else replace it.  Ignore + if it is the first occurrence of option.
AK
  743 11/17/07 VA P 1 Misc. mz390 corrections:
1) Correct mz390 to allow comment on macro proto-type statement following positional and keyword parms. 
2 )Correct mz390 to allow comments without leading comma on PR just like it does with 12 other instructions with no operands.
3) Set attribute type for CNOP label to 'I'.  Note length is unknown during lookahead mode.
4) Correct PUNCH processing to support comments following '...'
See rt\test\TESTASM1.MLC regression test.
AK
  744 11/24/07 VA E 1 Change mz390 and az390 to issue error if non-comment source statements contain non-printable ASCII characters.  This will help identify any character constants such as C'..' which must be converted to hex format X'....' for portability between EBCDIC and ASCII based host system.  See rt\test\TESTERR1.MLC AK
  745 11/25/07 VA E 1 Add mz390 support for the AREAD options CLOCKB, and CLOCKD and ignore options NOPRINT and NOSTMT. See rt\test\TESTASM1.MLC regression test. AK
v1.3.08e   11/17/07       PTF with cumulative fixes for v1.3.08

  735 11/12/07 VA P 1 Corrections to new linker LNK support plus a few misc. changes:
1) Change LNK to LKD to avoid conflict with Windows shortcuts
2)  Ignore CTRL-Z (hex 1A end of file codes in LKD source code
3)  Prevent trap when INCLUDE DDNAME is not defined
4)  Issue message ignoring all unrecognized command such as SETOPT and PARM(....)
5) Check for explicit .OBJ on lz390 file parm and ignore LKD
6) Assign default starting address of load module to matching EXTRN if there is no matching CSECT/ENTRY in load module.
AK
  737 11/11/07 VA E 1 Misc. corrections and enhancements:
1) Add mz390 warning message if non-comment type statements found after END statement with option ASM. 
2) Add option STATS(filename) to append all statistics output from mz390, az390, lz390, and ez390 to filename.STA.  Use of this option turns off statistics as comments at end of BAL, PRN, LST, and LOG files.  Spectify NOTSTATS for no statistics at all.
3) Correct spelling of "version" in IVP message.
4) Correct superzap spelling on command prompt
5) Correct superzap.bat rem, spelling, and remove pause
6) Correct superzap display of each command read once
8) Correct superzap SYSIN file I/O error to display error message and exit rather than issue user abend.
9) Correct z390 GUI interface to route all input to running CMD task until it terminates.  Enter exit or ctrl-break to force CMD end.
10) Update superzap web page documentation
11) Correct az390 assembler to handle Enn exponent modifier on F and H type constants.
12) Prevent trap on ASCII character literal conversion to EBCDIC for hex codes 00-ff.  ASCII with high bit maps to same EBCDIC character as ASCII with no high bit.  When converting EBCDIC source to ASCII for use with z390, translation use a tool that reports any hex literals with non-ASCII characters as errors.  These much be converted from C'...' to X'....' format for portability.
AK
v1.3.08c   11/09/07       PTF with cumulative fixes for v1.3.08  
  732 10/27/07 VA E 1 Add new lz390 linker optional input command file named linkfile.LNK  where linkfile is the linker parm anme.  The LNK command file may contain 1 or more sets of the following commands to create 390 load modules:
1)  INCLUDE DDNAME(name) - default is linkfile.obj
2)  ALIAS name - default no alias created
3)  ENTRY name - default is offset 0 in linkfile.obj
4)  NAME name(R) - default is to create single linkfile.390
The (R) is assumed if not present.  The default directory for the LNK command file is the same as the MLC source default directory.  ALIAS will generate 390 stub file which simply contains up to 8 character ASCII name of the real 390 program to execute.  These stub 390 files contain no OS dependent path characters and are portable between Windows and Linux.  The ALIAS and the real 390 program will be located using SYS390 directory option setting.
AK
  733 10/27/07 VA E 1 Consolidate all the TRACE options into one option using TRACE(AEGLMQTV) where letters represent the following:
 A - trace az390 assembler creating .TRA file
 E - trace ez390 instruction execution creating .TRE file
 G - trace all GETMAIN/FREEMAIN requests on .TRE
 L - trace lz390 linker creating .TRL file
 M - trace mz390 macro propcessor creating .TRM file
 P - trace nz390 macro pseudo code generation/execution on TRM
 Q - trace all QSAM DCB I/O data transfers on .TRE file
 T - trace all TCPIO messaging transfers on .TRE file
 V - trace all VSAM ACB I/O data transfers on .TRE file
The existing TRACE option is the same as TRACE(E) and the TRACEALL option is the same as TRACE(AEGLMQTV)
MM
v1.3.08b   11/07/07       PTF with cumulative fixes for v1.3.08  
  724 10/22/07 VA E 1 Change REPRO VSAM utility support as follows:
1) Support the following sequential unloaded file formats:
 
RECFM Prefix words Record Notes
EF none records up to 2 GB Default for fixed ESDS/KSDS (a)
EV LLLL records up to 2 GB Default for variable ESDS/KSDS (a, b)
RF RRN records up to 2 GB Default for RRDS, (a, c)
RV LLLL,RRN records up to 2 GB Default for VRRDS (a, b)
F or FB none records up to 32760 (d)
FT none ASCII text records (d), Converts to EBCDIC
V LL00 records up to 32760 (d,e)
VB BB00,LL00 records up to 32760 (d,e,f)
VT none ASCII text records (d), Converts to EBCDIC

Notes:
a) The default formats (EF, EV, RF, and RV) all use QSAM fixed format I/O changing the full word DCBLRECLF to read or write up to 2 GB at once.
b) LLLL is full word record length up to 2 GB including 4 or 8 byte prefix.
c) RRN Relative Record Number is full word starting with 1 for first record.
d)  F, FB, FT, V, VB, and VT alternate standard QSAM formats may be used by coding [RECFM=xx] following file name on corresponding INFILE or OUTFILE set statement.  Note unloading RRDS/VRRDS to alternate QSAM format file will skip unwritten records, and reload may assign different relative record positions form the original RRDS/VRRDS file.
e) LL00 is 2 byte record length including prefix followed by 2 byte zero.
f ) BB00 is 2 byte block length including prefix followed by 2 byte zero.  One or more LL00 prefixes and records may appear in a block.  Blocking is unnecessary as REPRO uses its own larger buffer to optimize performance.
2) Change VSAM RRDS structure to use VX0 index to point to non-null records with XRBA+1.  Null records contain 0 XRBA index values just like VRRDS and KSDS.  This saves space for sparse record files and simplifies detection of unwritten or deleted records.
3) Add REPRO buffer to reduce I/O's and improve performance using 500k buffer..
4) Add statistics showing record formats and total records.
5) Correct VSAM to raise no record found when randomly reading empty slot.
6) Correct RRDS to return RRN Relative Record Number starting with 1.
7) If RRN = -1, set to next RRN at end of file.
8) Return invalid request response for RRDS option ADR and ESDS option KEY.
9) For RRDS get with KEQ return no record found if null record.
10) For RRDS get with KGE return next non-null record.
See updated RRF1TEST, RRF1SKP1, RRF1REPO, RRV1TEST, RRV1SKP1, and RRV1REPO regression tests in vsam\test.

MM
  725 10/22/07 VA E 1 Remove -Xmx option from mz390.bat (no longer needed with 2GB memory on PC).  See updated EZ390.BAT comments documenting all the options available.  Add link to J2SE runtime options documentation. MM/DSH
  726 10/23/07 VA E 1 Suppress error 187 indicating first assembly address change if there are previous errors reported or the TRACE option is on. AK
  728 10/23/07 VA E 1 Enhancements to mz390/az390 to support assembly of Waterloo Assembler G source code available on the web from SHARE files at www.cbttape.org file #593 (43k lines of code in 44 MLC files with 2817 lines of macro code in 73 MAC macro files and 1 CPY copy file):
1)  Rename MVS macro DLETE.MAC to DELETE.MAC.
2)  Add support for ICTL start, end, continue source format control statement in the mz390 loading stage.  See ASMG source module ASMGBUFF.MLC as exmple using ICTL 1,71,20 which successfully assembles with continuation lines starting in col. 20.
2)  Ignore ICTL and ISEQ statements in the az390 assembly process.  The BAL file generated by mz390 is in standard ICTL 1,71,16 format with any ICTL and ISEQ statements included but ignored.
AK
  729 10/26/07 VA E 1 Add EXEC CICS DFHRESP response code ILLOGIC with value F'21'.  See updated rt\test\TESTCIC1 regression test. MM
  730 10/26/07 VA P 2 Correct LOG(filename) option to override the default program name for the LOG, TRE, and ERR execution output files using the same path as the program.   If there is no program path specified as in the case of REPRO and other utilities, then the current directory is used for LOG(files).  This enables creation of separate files for multiple programs with the same name running concurrently via CMDPROC started tasks. MM
  731 10/26/07 VA P 1 Change processing of CMDPROC started task output as follows:
1)  Optimize the methods used to sent and receive messages to/from started tasks using line at a time versus character at a time methods.
2)  Add option MAXLOG(mb) with 1 MB default.  When the visible GUI log exceeds the MAXLOG limit, the visible log will be truncated by 50% to prevent exceeding available memory.
3) Add option MAXQUE(messages) with 1000 default.  When the number of started task output messages queued in memory exceeds this limit, all output from started tasks is copied to the parent's log file to prevent exceeding available memory.
4)  Add keyword option CMDLOG=YES to CMPROC macro for use with START command to indicate that parent task should automatically route any started task output to the parent log file.  Log messages from started tasks will be prefixed with CMD ID=N.  If CMDLOG=NO is specified, the parent task must issue CMDPROC READ commands to retrieve messages from the memory resident started task output queue.
5) Issue yield after each output message from started task svc services to allow parent task to process message or copy message to the parent's log file. If the memory queue reaches MAXQUE limit for any reason, then messages will be copied to LOG and will no longer be available via CMDPROC READ commands.  
6) Correct error message 18 to say maximum trace file size exceeded instead of bal.  To increase maximum output file sizes from default of 50 MB, add option MAXSIZE(100) etc.
7)  Add support for CMD subtasks running J2SE programs to request parent task shutdown due to abort error such as file error.  Any CMD subtask can request parent abort by sending message "z390_abort_request" to standard output.  This allows CICS to shutdown gracefully without leaving hung local terminal processes.
See updated rt\test\TESTCMD1 and TESTCMD2 regression tests with new CMDLOG=NO added.

  712 10/02/07 VA P 1 Corrections to GUAM support for TN3270 screen used by CICS:
1)  Correct TGET with RC=4 returning data in buffer unexpectedly.
2) After CTRL-C clear screen, set cursor at (1,1).  This is to correct intermittent problem with cursor returning to cursor location from previous TPUT.
3) Correct code to prevent trap on bad index during interval timer exit for checking WTOR reply and timeout limits.
MM
  713 10/04/07 LX P 1 Corrections in order to successfully install z390 v1.3.08 on Ubuntu Linux 6.06 LTS and run all regression tests:
1)  Change iz390.java to match file name case for Z390.IVP.
2)  Correct RTLINK1.BAT to use lower case mac+linklib for UNREF assembly.
3) Correct RT.BAT to remove RTUTIL references and add vsam DIFF.TXT file for Linux.
4) Correct cmd.pl perl script to correctly handle SET commands where value contains = such as [RECFM=FT] in REPRO commands for testing VSAM.
5) Add new command COMP1.BAT to handle both Windows and Linux file compares using fc or diff creating difference file and setting rc to non-zero if files have differences other than while space.
6) Correct file I/O to check for relative path and prefix with current directory as defined in J2SE since Linux and Windows are inconsistent with respect to current directory used by file handler.
7) Update cmd.pl to pause and then exit if unknown BAT command attempted.
VS reported error in perl scripts but with the corrections above I was able to run all regression tests including vsam with no errors on Linux with J2SE 1.5.0_13.

  717 10/11/07 VA P 1 Set r15=0 for all TIME svc options if successful else R15=4. DSH
  718 10/14/07 VA E 1 Enhance OPEN and CLOSE macros to issue error if register symbol not enclosed in extra (reg) such as OPEN (r1) versus OPEN ((r1)).  MM
  719 10/14/07 VA E 1 Add option on LOG command to specify log, trace, and error file name override in the form LOG(filename) which overrides the default pgmname with .LOG, .TRE, and .ERR file names.  This option should be specified whenever launching multiple tasks which have the same program name to create unique log, trace, and error files. MM
  720 10/15/07 VA E 1 Eliminate recursive error message following error 39 for missing MLC source file. DSH
  722 10/18/07 VA P 1 Correct WTOR to flush cmd input queue from std in for current process in order to get reply from next cmd input msg send by parent task which may be any of the 3 following sources:
1)  Console input if program executed from command line
2)  z390 GUI which passes on console input if cmd process running
3)  parent cmd process which may issue cmd input to spawned process after receiving it from any of the 3 options.

v1.3.08   10/02/07       Full release with initial VSAM ESDS, RRDS, and KSDS support.  
  676 08/14/07 VA P 1 Correct IVP version files to match release. PK
  684 08/23/07 VA E 1 Change utilities as follows:
1)  Move all utilities including REPRO, SUPERZAP, and UNREF to linklib directory which is now on the default 390 execution path for EZ390 command.  The util directory is being removed. 
2) Change SUPERZAP to test if SYSIN command file defined and if not default to PARM(CON) for console input.
3)  Add the following new utility commands in z390 directory:
a)  REPRO.BAT - INFILE=%1, OUTFILE=%2
b)  SUPERZAP.BAT - SYSIN=%1.ZAP, SYSPRINT=%1.RPT
b)  UNREF - PRNFILE=%1.PRN, URFFILE=%1.URF  
MM/DSH
  678 08/18/07 VA E 1 Add initial KSDS support.
1)  See vsam\demo\KSF1RPO1.BAT which uses REPRO to load KSF1NAME cluster and primary index from text file KSF1NAME.TF1 containing 6 records with name, address, etc.  Then it uses REPRO to unload fKSDS file to ascii text file KSF1NAME.TF2 and compares it to the original input file.
2) See vsam\demo\KSF1DEMO.BAT which reads 6 records in KSF1NAME KSDS file in reverse order via primary key access.
Run RTVSAM.BAT to run all VSAM regression tests and demos.
3) See vsam\demo\KSF1SKP1.MLC which does POINT for key MQ with RPL option KGE and then reads and lists records sequentially to end of file.
DSH
  693 09/10/07 VA E 1 Add VSAM random access performance improvement by caching read only index I/O.  Add option VCB with default on indicating VSAM Cache Buffering operational.   To see VSAM I/O statistics without any buffering specify option NOVCB.  In the KSF1DEMO.BAT using VCB reduces the primary KSDS index file read I/O's from 15 to 6 plus 9 cache reads. DSH
  700 09/19/07 VA E 1 Add linklib directory to end of SYS390 load lib search in order to execute REPRO, SUPERZAP, UNREF and other utilities in linklib without requiring path.  DSH
  706 09/28/07 XP P 1 Misc. VSAM corrections:
1)  Correct POINT to set FDBK and return code correctly.  Note all VSAM files are limited to MAXSIZE(mb) option setting which defaults to 50 MB. VSAM files using RBA vs XRBA are limited to 2 GB (31 bits) regardless of MAXSIZE setting.
2) Store RBA or XRBA in RPLARG on sequential GET or PUT for ESDS and check limit.
3)  Check file size limit on all VES reads and writes.
4) Check RBA/XRBA for fixed ESDS for multiple of record length.  There are no other consistency checks of positive RBA/XRBA for variable length ESDS or KSDS files currently. 
MM
  707 09/28/07 VA E 1 Change default maximum number of concurrent files in use to 1000 versus previous 10,000.  This can be overridden with MAXFILE(..) if necessary for very large macro assembly. DSH

v1.3.07f   09/27/07       PTF with cumulative fixes for v1.3.07 plus GENCB support.  
  701 09/20/07 VA E 1 Change REPRO default to replace existing VSAM files during load processing rather than adding records unless OUTFILE has overide [DISP=MOD] specified after catalog.entry name. DSH
  702 09/20/07 XP P 1 Change ESDS  and RRDS support as follows:
1)  Require use of POINT to set ESDS current RBA/XRBA position prior to GET for SEQ FWD or BWD RPL's.  Allow use of RBA/XRBA of high values for POINT  to indicate end of file.  See updated ESF1SKP1 and ESV1SKP1 regression test changes.
2) Require use of POINT to set current position prior to GET for SEQ FWD or BWD.  Support with LRD or high value record number or RBA/XRBA to position to end of file.  See new ESF1SKP1, ESV1SKP1, RRF1SKP1 and RRV1SKP1 regression tests.
3) Change ACB and RPL option DIR to KEY for random access to RRDS and VRDDS by record #.  See all demo and test RRDS/VRRDS programs.
4) Change TRACE format for both VSAM and TCPIO svc's to show the name of the specific operation being requested based on opcode in R0.  For example you can now search for "VSAM POINT" in trace.
5)  Change positioning support to always store current VES or VX0 XRBA address in RPLCXRBA field.  Store last record XRBA in RPLLXRBA else store -1.  Reset RPLLXRBA to -1 and RPLCXRBA to 0 when new or reopened ACB is detected for RPL.
6) For ESDS sequential access, return current RBA/XRBA for each record in RPLARG.  See updated ESF1SKP1 and ESV1SKP1 regression tests.
8) For RRDS and VRRDS sequential access skip null records created by system and return relative record # in RPLARG.  See updated RRF1SKP1 and RRV1SKP1 regression tests.
MM
  703 09/20/07 XP P 1 Correct GENCB macro missing quote in AIF following label WAREA2.  Correct ZGENRPL and ZGENACB macros to ignore 0 value fields rather than redundantly storing 0.  See reduced code generated for ESF1SKP1 and ESV1SKP1 tests. MM
  704 09/23/07 VA E 1 Add VSAM catalog support for CONTROLINTERVALSIZE= on CLUSTER to force CI padding so VES file can be processed as LINEAR reading CI block at a time.  See updated ESF1CI2K and LDS1CI2K catalog entries in vsam\test\TESTCAT.MLC. DSH
  705 09/25/07 VA E 1 Add new z390 VSAM RPL Operation Regression Tests Documentation showing RPL functions and options specified for each regresson test. DSH
v1.3.07e   09/18/07       PTF with cumulative fixes for v1.3.07 plus GENCB support.  
  682 08/20/07 XP E 1 Add GENCB macro support for dynamic ACB and RPL creation:
1)  Change OPEN to generate required DCBD for option flag refs.
2)  Correct RPLD name of RPLID field.
3)  Add ZGENMACF and ZGENOPTD macro to support MACRF= and OPTCD= option bit generation shared by ACB, RPL, and MODCB.
MM
  696 09/15/07 XP P 1 Correct misc. VSAM errors:
1)  Correct ZMODCB error to handle 1  byte fields which caused error MNOTE trying to change MACRF or OPTCD fields.
2)  Correct REPRO to verify successfully loaded catalog file is a VCDT catalog before assuming DDNAME is a VSAM catalog reference.
3)  Add support for MODCB default option parms for RPL OPTCD - FWD to turn bit off in RPL with BWD set. Note all the required OPTCD option bits in ACB MACRF or RPL OPTCD must be specified since MODCB replaces the entire field with new options specified.  Add support for RPL= and ACB= which means that the RPL fieldfor ACB address is being updated.
MM
  697 09/17/07 XP P 1 Correct QSAM\VSAM related I/O support as follows:
1) Correct DCB variable GET and PUT to allow 5 byte variable length records with 1 byte of data.  Previously errors 28 and 35 were issued for 1 byte variable length records in error.
2) Change REPRO to accept override of QSAM RECFM for fixed or variable length from default of F or V to FT, FB, VT, or VB by specifying the RECFM required in brackets after file name.  For example:  SET INFILE=TESTVT.TF1[RECFM=VT].  See vsam\test\ESF4REPO.BAT and ESV5REPO.BAT regression tests.
3) Correct feedback for ESDS invalid RBA to use reason code  x'32' versus x'c4' which is for RRDS only
4) Correct RPL processing init to always refresh ACB and VCLR fields.  Correct ACB.  Correct ACB processing init to always refresh VCLR fields as well. 
4)  If ESDS RPL has ADR and SKP, then set current position on each RBA/XRBA get for possible following SEQ GET.  For BWD be sure both ADR and SEQ RPL's also have BWD set.  See updated vsam\test\ESF1SKP1.MLC and ESV1SKP1.MLC regression tests.
5) Add option TRACEQ to trace all QSAM GET/PUT file I/O similar to TRACEV for VSAM file I/O.
6)  Correct QSAM VT input support to handle ascii line with no characters other than cr,lf and create 5 variable length input record with single space since 5 is the minimum QSAM record length.  See regression test vsam\test\ESV5REPO.BAT.
7)  Set R15=0 return code for SHOWCB, TESTCB, MODCB.
MM
v1.3.07d   9/14/07       PTF with cumulative fixes for v1.3.07 and VSAM enhancements  
  672 08/24/07 VA E 1 Correct and enhance VSAM ESDS and RRDS support as follows:
1)  Correct ESDS and fixed length RRDS to read and write directly to VES data file with no VX0 index required.   RBA and XRBA now point directly to VES records. 
2)  Add ESDS update option UPD.  Updates must be for same length record in place via PUT after successful GET.  See new regression tests vsam\test\ESF2TEST and ESV3TEST tests.
3)  Add ESDS option BWD for fixed and variable length sequential read backwards.  For variable length ESDS, this requires adding redundant record length following each record in order to sequentially traverse file backwards with no VX0 index.  See regression tests vsam\test\ESF3TEST and ESV4TEST.
4) RRDS variable length files (also known as VRRDS) will continue to use VX0 to map relative record # into XRBA for VES data file access.  Rewriting VRRDS record with different length causes record to be written  at  end of VES leaving prior record area  as dead space until next unload/reload.  See regression test vsam\test\ESV3TEST.
5) Correct to always use RPL flags  vs ACB flags to  determine which type of access to use.  Correct RPL macro to issue error for undefined options.  Verify RPL vs ACB for MOD,TEST,SHOW.
MM/DSH
  694 09/11/07 XP E 1 Add new option ERRSUM to list critical error summary on PRN, ERR and console.  Missing macros and copy files are listed if any.  If none, then any remaining undefined symbols are listed.  This option highlights missing macros and copybooks as first priority to correct.  Once all macros and copybooks are found option ERRSUM will list any remaining undefine symbols which usually indicate a missing macro or copybook such as a DSECT.  This option is automatically turned on by the macro assembler when missing macros or copy files are detected.   To override this option, specify ERR(0) to force assembly regardless of critical errors.  This option may need to be used several times to find and fix nested missing macros and copybooks.  Any remaining undefined symbols in an assembly now appear in the symbol table with TYPE=UND.  For an example try assembling the REPRO VSAM utility with the command ASM linklib\REPRO SYSMAC() SYSCPY() which suppresses the default libraries and causes ERRSUM option to be turned on to show 2 missing copy files and 24 missing macros causing 25 undefined symbols. AK
  695 09/12/07 XP P 1 Correct mz390 macro processor to replace single null macro call parameter on inner macro call with comma if space delimited comments follow the parm to prevent the first word in comments from being parsed as call parameter in error.  See updated regression test rt\test\TESTMAC1. AK
v1.3.07c   09/07/07       PTF with cumulative fixes for v1.3.07 and new VSAM catalog  
  681 08/20/07 XP E 1 Redefine VCDT from VSAM Cluster Definition Table for single VSAM file to VSAM Catalog Definition Table (VCDT) which is created using multiple DEFINE macros to define a catalog with multiple base clusters, alternate indexes, and paths.  The DDNAME on ACB points to the VCDT catalog loadable file with optional dot suffix defining name of entry to open.  Alternatively the ACB name field is used to find base cluster or path entry in the catalog.  This was requested by Melvyn and provides more flexibility and compatibility with existing VSAM application code.  The new catalog supports UPGRADE option on each alternate index and supports using  PATH pointing to base cluster with no updating of alternate indexes if desired.  See updates to VCDTD, ACBD, and RPLD for new entries (application programs should use SHOWCB, TESTCB, and MODCB rather than these internal control blocks).  All bit flags in these DSECTS have been changed to single byte values.  See updates in vsam\demo  and vsam\test to use new DEMCAT catalog for all the demos and TESTCAT  for all the regression tests.  Also see updates to vsam\test\ESV1TEST.MLC to verify RBA and XRBA read records randomly. MM
  690 09/03/07 XP P 1 Misc. corrections and additions:
1) DFHRESP code NOTEND to be NOTFND.
2)  Add MODCB RPL= support for ARG= and OPTCD= options.
3)  Add MODCB ACB= support for MACRF= options.
4)  Correct SHOWCB undefined &TARGET variable.
MM
  691 09/03/07 VA P 1 Correct mz390 GBLB definition termination when only 1 space following subscript before continuing comments. DSH
v1.3.07b   09/1/07       PTF with cumulative RPI fixes for z390 v1.3.07  
  683 08/23/07 XP P 1 Correct REPRO errors and add additional regression tests:
1) Correct SYNAD addresses being moved to wrong DCB.
2) Correct prefix support for variable length VSAM to QSAM.
MM
  685 08/23/07 XP P 1 Correct DCB FT and VT format translation to ignore nulls rather than treating them as end of record indicators. DE
  687

 

08/25/07 XP E 1 Add the following additional DFHRESP response code literals for future CICS VSAM support: 
FILENOTFOUND = F'12'
NOTFND = F'13'

  688 08/25/07 XP P 1 Correct and expand initial VSAM support as follows:
1)  Correct open/close to issue return code for errors.
2)  Add ESDS direct access by 4 byte RBA or 8 byte XRBA.
3) Support RPL=(reg) plus optional field SCON formats in MODCB, TESTCB, and SHOWCB.  Add SHOWCB fields RBA and XRBA. 
4) Change ACBD, RPLD, and VCDTD DSECT maps to split  option flags into separate  bytes with 1 byte EQU's.
5) Change ESF1 demo  to use 3 - 80 byte fixed length records.
6) Change ESV1 demo to use 3 variable length records with 100, 200, and 300 bytes of data.
7) Add the following VSAM tests in vsam\test directory:
a.  ESF1TEST - create and verify ESDS file  with 3 fixed length records using sequential, RBA, and XRBA  access.
b.  ESF1REPO - load and unload ESF1 fixed length record ESDS  file using REPO and verify.
c.  ESV1TEST - create and verify ESDS file  with 3 variable length records using sequential, RBA, and XRBA  access.

f.  RRF1TEST - create and verify RRDS file with 3 fixed length records at relative record 0, 2, 4.
g.  RRV1TEST - create and verify RRDS file with 3 variable length records at relative record 0, 2, 4 with lengths 100, 200, and 300.
8) Add new z390 option TRACEV to trace and display  all data read or written to VSAM data or index files.
MM
  689 08/26/07 XP P 2 Correct option TRACET to support TS timestamp option without requiring TRACE option on to allow generating TRE file with just time stamped data transfers for TCPIO and TGET/TPUT.  All TEST output and memory dumps go to TRE file.  Log messages will appear on both TRE file and log file. MM
v1.3.07a   08/22/07       PTF with cumulative RPI fixes for z390 v1.3.07  
  630 05/30/07 XP P 1 Correct GUAM and misc. CICS support as follows:
1
) Correct pixel size of screen letters to prevent clipping and residual cursor underline pixels being left on screen.
3) Correct delete key to delete character in input field and shift remaining characters in input field left.
4) Change font size to maximum for full screen display when window is maximized or resized.
5) Consume KeyPressed event PF10 after processing for AID key input to avoid Windows PF10 annoying "File" menu popup.
6) Correct recursive update loop that was causing memory leak when running in TN3270 screen display mode.
MM
  670 08/04/07 XP E 2 Correct TCPIO and other macros to eliminate unnecessary LR instructions when target equals source register (A new macro ZOPTLR is now used in all z390 macros to optimize the LR instruction).  Correct mz390 TRACEALL option to correctly display AIF compare values in correct numeric values for SETA and SETB type compares (was showing empty SETC values in error). MM
  671 08/05/07 XP P 1 GUAM CICS and TN3270 Enhancements (1 moved from RPI 557):
1) Correct TGET with ASIS when no attributes set.
2) Add TRACET option to dump TGET/TPUT buffer data being passed similar to TRACET support for TCPIO messaging.
3) Correct 2 display bugs in trace for TGET/TPUT buffer addr and length.
MM
  673 08/11/07 XP P 1 1) Correct mz390 to allow symbolic substitution for macro proto-type name in inline macro definitions.  See updated rt\test\TESTMAC1.MLC.
2)  Correct az390 to support symbolic expressions in DROP statement such as A2+1 where A2 is EQU symbol.  See updated regression test rt\test\TESTASM1.MLC.
3)  Correct LA of complex expression which reduces to relocatible expression.  SPITBOL 24k source can now be assembled without error.
JL
  674 08/12/07 VA E 1 Update linklib\CVTTOHEX.MLC conversion routine to translate bytes to HEX using single TROT in place of UNPK/TR loop to  perform translation for any length area.  Suggested by Melvyn who is using TROT in EXEC CICS support now. DSH
  677 08/17/07 XP P 2 Correct DCB PUT support to only check end of variable length record area rather than maximum record length to prevent erroneous 0C5 using v1.3.07 with RPI 668 buffer checking. DE
  680 08/19/07 XP P 1 Correct VSAM macros as follows:
1)  RPL - correct OPTCD loop test from GE to GT and define &LRD as LCLB.
2)  TESTCB - change SHOWCB to TESTCB in MNOTE.

v1.3.07   08/11/07       Full Release with initial z390 VSAM support for ESDS  
  72 10/01/05 XP E 1 Add initial VSAM support.  Use DEFINE macro to assemble and link loadable VSAM cluster definition table with ESDS data file and associated RRDS and KSDS index file DCB's.  Use new REPRO utility to load or unload VSAM cluster files from or to QSAM file.  See z390 VSAM User Guide (partial draft) plus demos and regression tests using macros ACB, CLOSE, ERASE, GET, OPEN, PUT, PUTX, RPL, POINT, SHOWCB, and TESTCB. DSH
  644 08/03/07 VA E 1 Update or add the following macros for initial VSAM ESDS support: ACB, ACBD, CLOSE, DEFINE, ERASE, GENCB, GET, MODCB, OPEN, POINT, PUT, RPL, RPLD, SHOWCB, TESTCB, and VCDTD.  The DEFINE macro supports creation of loadable VSAM Cluster Definition Table (VCDT) which serves as equivalent of VSAM cluster catalog definition.  The new ACBD, RPLD, and VCDTD macros provide DSECT layout of ACB, RPL, and VCDT control blocks, but for mainframe compatiblity only SHOWCB, MODCB, and TESTCB should be used to access ACB and RPL fields.  A new utility linklib\REPRO supports loading or unloading VSAM file from/to QSAM files or anther VSAM file.  See the z390 VSAM Support online page for more information and links to references and examples.  DSH
  664 07/23/07 VA E 1 Update z390 Regression Testing web page with all regression tests as of v1.3.06 and update regression test as follows:
1) Add interactive regression testing of soa\test programs to test TCPIO basic client/server messaging programsTESTMSGC and TESTMSGS.  Fix parm and TCPIO macro options.  Run RTSOA.BAT interactive test to verify assemble and link and run tests.
2)  Add RTCICS.BAT which runs the cics\DFTALL command to assemble and link all CICS commands and then runs server and remote client on same processor to test interactively.   This required adding cics\save and cics\dif directories for comparison and difference files.
DSH
  665 07/24/07 VA E 1 Update z390 EXEC CICS Compatible Assembler Support website documentation with links to PDF documentation by Melvyn Maltz. DSH

  667 07/30/07 VA P 2 Correct az390 to issue error 197 for invalid binary value string. DSH
  668 08/02/07 VA P 2 Correct shared DCB and ACB support as follows:
1.  Issue 0C5 if GET/PUT/READ/WRITE i/o references invalid memory area.  Previously I/O error due to Java trap could occur.
2.  Change OPEN and CLOSE macros to test return code for each svc and exit if non-zero.  VSAM always returns to caller with return code rather than abend abort.
3.  Set DCBOFLGS to zero in DCB and set bits at OPEN based on OPEN options.
4.  Use current VCDT file path for each DCB opened for ACB open.
5.  Issue DCB SYNAD error if lrecl/blksize 0 on get/put to prevent i/o error or loop.
6.  Show DCB and ACB access statistics for STATS option on the LOG and TRE files.
DSH
  672 08/09/07 VA P 1 Correct pz390 to prevent EX target instruction code 2nd byte from being left set to modified state when running with TRACE and undefined opcode is incountered prior to EX. MM
v1.3.06a   07/22/07       PTF with cumulative fixes for v1.3.06  
  657 07/17/07 VA P 1 Work-around for Windows Vista to allow running z390 using default install directory  in "C:\Program Files\....\z390" - Turn off Vista UAC option via the Control Panel, User Accounts dialog.  This will allow spawned command line tasks to automatically obtain administrator permission required to access the "C:\Program Files" directory as of Vista updates applied between 07/08/07 and 07/15/07.  

For more information about Vista UAC visit the following web sites:
    Microsoft Vista User Account Control Option

Turning Vista UAC option off is hopefully a temporary solution to allow users to install z390 in the default directory on both XP and Vista and be able to achieve compatible results.  The only other current work-around is to install z390 into a directory such as C:\z390 which is not protected like "C:\Program Files\..." on Vista.

Although turning off Vista UAC may appear to be increasing security risk, as long as security software such as Windows or Symantec fire wall is active, the risk should not be any higher that it was  with Windows XP. 

DSH
  658 07/17/07 VA P 1 Correct regression tests for new vse and util director programs:
1)  RT.BAT - change RTCLEAN.BAT to DIRCLEAN.BAT
2)  RTDEMO1.BAT - add STDDEVLB.MLC demo std. deviation
2)  RTVSE.BAT - remove assembly of demo\DEMO
3)  DEMOVSE1.MLC - use SUBENTRY/SUBEXIT vs EOJ
4)  DEMOVSE2.MLC - use DEMOVSE1 for CDLOAD and EOJ
5)  Remove erroneous UNREF (2).BAT files from util\unref\save
DSH
  659 07/18/07 XP E 1 Change z390 assembler error messages to be more compatible with HLASM as follows:
1) If opcode has invalid character, issue invalid opcode character error 196 versus undefined opcode error 29 in az390.
2) Issue invalid label symbol error 218 in mz390 if macro variable substitution for label field inserts any invalid label character including * or period in first position.
3) Cleanup all trace and log files to remove duplicate pgm ids and duplicate statistics messages for assembler.
See new regression test rt\test\TESTLAB1-3.MLC.

  550 02/03/07 XP P 2 Correct PRN listing to show correct line numbers for source statements following COPY statements.  Currently the line # shown includes the lines from the copy files.  Display all COPY statements in MLC file, and display the file #, file line #, and the generated BAL line # on all PRN statements listed.  See RT\TEST\TESTCPY1.MLC regression test. RM
  551 02/09/07 XP P 2 Fix CMDPROC macro to support ID=(reg) where reg contains process id, and correct error in support for ASCII mode affecting both CMDPROC and WTOR which store text in memory.  Both RT\TEST\TESTCMD1.MLC and RT\TEST\TESTCMD2.MLC will now run correctly in ASCII mode.. MM
  552 02/09/07 XP P 2 Correct error messages to reference GUAM versus GUI for clarity. MM
  553 02/09/07 XP P 1 Correct assembler to flag the following symbol errors:
a)  Duplicate symbol on both CSECT and DSECT.
b)  Duplicate symbol on CSECT, DSECT, or LOCTR and other statement such as EQU/DS/DC unless address matches.
c) Symbol on more than one EQU.
See corrections to RT\TEST\TESTDST1.MLC caught by this fix.  See RT\TEST\TESTERR2.MLC for updated tests.
MM
  554 02/09/07 XP P 1 TCPIO sockets support fixes and enhancements:
a)  Close all open TCPIO ports during shutdown.
b)  Add NOWAIT option for TCPIO RECEIVE which will return with RC=4 if no message is ready.
c) Eliminate LMAX parm from OPEN and just use LMSG on RECEIVE to limit input message size.  Each RECEIVE will return up to LMSG bytes with actual bytes returned in R1.  Increment MSG address, decrement LMSG by bytes read, and repeat RECEIVE until the desired number of bytes have been read.  The number of bytes read will usually be the same as the number sent unless the network is stressed and the packet size has been reduced.
d) Support up to 20 connections on up to 10 server ports.
e) Add CONN= referencing register or RX location of 4 byte integer server connection id for use in SEND to server PORT.  The server port RECEIVE returns the connection id in R2.
f) Add option TRACET to trace only TCPIO events on TRE file.  The TRACE option defaults to include TRACET.
See updated SOA client server demo in soa\demo.  See new SOA test programs in soa\test including client TESTMSGC.MLC and server TESTMSGS.MLC for manually testing multiple port connections.  Multiple copies of the SOA demo client can also be run in parallel using the same single demo server.

1.3.01   02/08/07    
Maintenance and enhancement release with integrated support for Linux including updated regression tests run on Windows and Linux plus hyper RPI 542 compatibility fix for GETMAIN and STORAGE svc to place address in R1 and length in R0.  Previously only address was returned in R0.  
  532 01/08/07 LX E 2 Merge Linux support programs contributed by Martin Ward to support installation of z390 on Linux.  With these changes the z390 file zip can be installed following this Linux Installation Guide:
1)  Add "z390" perl script file to the z390 root directory.  This script can be executed directly from Linux terminal command line or desktop launcher icon with no operands to start z390 GUI Interface or with options and file name to assemble, link, and/or execute assembler program.  Changes to this script include:
   a) Set current directory to z390 directory before starting GUI
2) Add "cmd.pl" perl script file to the z390 root directory.  This script is used to emulate cmd.exe Windows command processor to support execution of the following BAT file commands: rem, erase, copy, call,  and java class execution.  Changes to this script include:
    a) Support paths to bat files where paths must be correct case and
        bat file names must be uppercase. Default suffix is .BAT..
    b)  Convert bat file "\" path delimiters to "/".
    b)  Allow upper and lower case commands and labels in BAT files
    c)  Support the following BAT file commands used in z390 tests:
         call, copy, dir file, diff dir1 dir2 file3, erase, exit, goto
         if errorlevel 1 goto label
         if errorlevel 1 pause (aborts on error currently)
         if exist file goto label
         pause (aborts after message currently), rem, set
3) Change z390\Doc directory to z390\doc for case consistency which was causing the "help, "guide" menu item to fail on Linux which is case sensitive so all paths and file names.
4) Change tz390 default text editor for Linux to "gedit" since it is already installed on base Ubuntu Linux and is a lightweight GUI editor similar menu to notepad plus support for multiple open files similar to Word.
5) Change all z390 RT BAT and data file names to upper case for consistency.
6) Change RTCOMP.BAT and RTLIST.BAT to test for Linux and use Linux diff command if running under cmp.pl on Linux.
7) Add option INSTALL(path) to debug z390 source with specified install path instead of default current path.
8) Change az390 to force macro names to uppercase for file search on Linux which requires all macro files to be uppercase.
DSH
  542 01/21/07 XP P 2 Correct output registers for STORAGE and GETMAIN RC/RU/R/VRC/CRU to return address in R1 for mainframe compatibility.  For GETMAIN VRC/VRU return length rounded up to multiple of 8 in R0.  See regression test corrections to
1)  SOA\MACLIB\SOACMGR.MLC - SOA client msg mgr
2)  SOA\MACLIB\SOASMGR.MLC - SOA server msg mgr
3)  RT\TEST\TESTMEM1-4.MLC - memory management tests.
4) CICS\DFHEAI0.MLC - CICS dynamic storage allocation
5) CICS\CICS.MLC - CICS command prompt work area alloc
See updated z390 Storage Services documentation contributed by Melvyn Maltz.
RM
  543 01/23/07 XP E 1 Add pause to generated SOA\DEMO\DEMORUN.BAT after start of SOA demo server before starting client to allow time for server to open port.  Also generate separate DEMORUNS and DEMORUNC server and client execution files for testing on different processors and operating systems on TCP/IP network. DSH
  544 01/23/07 XP P 2 Correct instruction trace format for DLG and MLG   Trace was showing r1 value instead of r1+1 value.. RM
  545 01/28/07 XP P 1 Correct sz390 svc 34 for CMDPROC to correctly honor user specified timeout interval in milli-seconds.  It was not returning RC=4 whenever the next input was not read instead of retrying until timeout limit exceeded. MM
  546 02/02/07 XP P 1 Change tz390 to correctly handle SYSERR and SYSTERM options with default systerm pgmname.err file in program directory.  If SYSERR specifies path, then all systerm .ERR files will be placed in that directory using pgmname.err.  If SYSTERM is specified with just name, then the file will go into SYSERR directory.  Path and name may be specified in SYSTERM. MM/DSH
  547 02/03/07 XP P 1 Change sz390 svc 34 for CMDPROC STOP to close standard input, output, and error prior to process distroy to prevent spurious thread errors.  Change rt\test\TESTCMD1.MLC and rt\test\TESTCMD2.MLC to eliminate Windows dependent PROMPT command, add search for REM END, and add error limit incase process fails on Windows, Linux, etc. DSH

MM/DSH
  537 01/18/07 XP E 1 Add z390 v1.3.00 Linux download zip contributed by Martin Ward with the following components required for z390 GUI and command line execution using Linux:
1)
cmd.pl  - Emulation of cmd.exe for handling simple batch files
2) z390     -  perl script for running the z390 GUI and command line
3) src/mainClass.txt - main z390 class for compiling under Linux
4) DOIT: shell script for compiling z390.java under Linux
See RPI 532 for integration of perl scripts in z390 v1.3.01.
