  822 03/15/08 VA P 2 Misc. corrections to v1.4.01:
1)  Correct BRC 3,*-4 in TESTINS3 to BRC 1,*-4.  Since CC2 is never raised it didn't fail.  See updated rt\test\TESTINS3.MLC.
2)  Add AUTOLINK to STATS option statistics file display.
3)  Correct trace format for LGFR type instructions to only show low 32 bits of r2.
4) Prevent trap in mz390 for opcode with no operands when they are required.		 DSH
  823 03/15/08 VA P 1 Correct the emulation for the MVCIN instruction to move assuming the second address is the right most byte of the source field rather than the left most byte.  See updated rt\test\TESTINS2.MLC. LC
  824 03/17/08 VA P 1 Correct FP as follows:
1)  When replacing 2nd FP register in extended precision pair, flush value in both registers before replacement.
2)  Correct DDTR, DXTR, DXR, DXBR to prevent storing null value in FP register  when divide by zero is suppressed which can later cause trap in SNAP dumps or other instructions accessing the same register.  This could only occur if no other instructions of the same FP type have been executed prior to the divide.		 BL
  825 03/18/08 VA E 1 Convert 20 year old PC/370 demo program SIEVE.ALC to run on z390 and include as new demo\SIEVE.MLC demo:

2)  Upgrade called subroutines DAT.ALC  to linklib\DAT.MLC  callable object modules to display JDBC format date and time via WTO with extensions to show nano-seconds plus total instructions executed, and MIP rate for interval since the previous call to DAT.
2)  Add new extended option TIME INS to return current z390 64 bit instruction counter in R1.   (Used by linklib\DAT.MLC). 		DSH
  826 03/19/08 VA E 1 Add new benchmark program bmk\BMKINS1.MLC to measure MIP rate for z390 instruction loop using the linklib\DAT.MLC callable routine.  This program can be used to measure effect of changes to z390 emulator such as the addition of trace table for indicative dump and optimization of instruction code.  The BCT reg,* instruction runs at about 3 MIPS on a Dell 2.1 GHZ duo core chip. DSH
v1.4.01   03/14/08       z390 Full Release with new z10 instructions and ASSIST support  
  811 02/26/08 VA P 1 Correct DFP bugs:

11) XPUT    X'E0C' RXSS s1,s2 write s1(s2) to DDNAME=XPT
12) XREAD X'E00' RXSS s1,s2 read s1(s2) from DDNAME=XRD
This support is being added in response to request from Northern Illinois University for  use in computer science  assembler classes.  Other education institutions are welcome to use it as well.  See assist\DEMOAST1.MLC and assist\TESTAST1.MLC assembler regression tests with the new ASSIST instructions.  See updated rt\test\TESTINS1.MLC for regression test of assembly of new ASSIST instructions when option ASSIST specified.		 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
  816 02/27/08 VA P 1 Correct pz390 execution hyper bug in LDR and LXR when source register has not been cached yet following LD.  DSH
  817 02/28/08 VA E 1 Add 226 new z10 instructions per POP V6:
1) Add support for assembly of all 226 instructions.  See updated regression test rt|test\TESTINS1.MLC for assembly of all the new z10 instructions. 
2)  Add emulator support for execution of new z10 problem state instructions.  See new rt\test\TESTINS3.MLC for new problem state instruction tests.
a) The MVCOS now supports true lengths up to 31 bits which is an extension of previous z390 MVCOS instruction support for up to 4096 bytes based on SHARE publication used in RPI 606 dated 04/26/07.  When true length is greater than 4096 the MVCOS instruction sets CC3.  See rt\test\TESTINS3.MLC for test.		 DSH
  818 03/09/08 VA E 1 Regression test v1.4.01 using J2SE 1.6.0_05 lastest update 5. DSH
  820 03/11/08 VA P 1 Misc. corrections to pz390 emulator support:
1)  Correct all shift instructions (SRP, SR??, SL??, RLL, and RLLG) processing to prevent S0C5 when b2 base register is negative.
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.		 DSH
v1.4.00f   02/22/08       PTF with cumulative fixes for v1.4.00  
  807 02/19/08 VA P 1 Publish updated macro KSIRD.MAC with 2 new fields for low and high branch height used in AVL balancing of KSIT tree with KSIR nodes. DSH
  808 02/20/08 VA P 1 Correct pz390 as follows:
1) Prevent trap on trace of LA when address higher than max memory and show value of -1 instead.
1) Prevent HFP and BFP underflow exception for multiply operations when one of the two operands is exactly zero or for divide when the divident is exactly zero.  See new contest problem mfacc\P12DSH2.MLC to calculate standard deviation in HFP and P11DSH3.MLC to calculate standard deviation using only DFP instruction.  All solutions correct to within 33+ decimal places.		 DSH
v1.4.00e   02/18/08       PTF with cumulative fixes for v1.4.00  
  806 02/08/08 VA E 1 VSAM fixes and enhancements:
1) Add automatic balancing of insert KSIT tree using AVL balancing technique to maintain even tree depth after inserts.
2) Add verification of all double links between KSIT and KSIR's.
3) Add verification of all KSIR heights in KSIT balanced tree.
4) Add AVL statistics to VSAM statistics for STATS option
5) Improve VCB cache size for optimizing VSAM I/O
4) Add regression test vsam\test\KSF2TST4.BAT which tests inserting 1000 records in pseudo random sequence and then fetching them by key sequentially to test AVL rotations LL, LR, RR, RL and verify KSIT tree has only 10 levels (2**10=1024).  With cache on, the resulting file I/O to insert and then fetch 1000 records is about 10,000 or 10 I/O's per record.  VSAM KSDS insert can be used as a sorting tool with the efficiency comparable to shell sort where I/O is proportional to N * log2 N.

  714 10/08/07 VA E 1 Upgrade to J2SE 1.6 upgrade 3 base for building z390.jar which means J2SE 1.5 runtime is no longer supported.  If you try to run z390 v1.4.00 on J2SE 1.5 runtime, an error loading class will occur.  Remove the J2SE 1.5 runtime and install J2SE 1.6.0_03+ runtime. DSH
v1.3.09   01/23/08       Full release for Windows and Linux - last build on J2SE 1.5.0_12  
  716 10/10/07 VA E 1 Move all save directories used for regression test verification to the rt optional install sub-directory to reduce size of the standard z390 install zips.  Also move all the rt command files from root directory.  After installing optional MVT.ZIP and RT.ZIP in z390 install directory, run rt\RT.BAT to run regression tests and compare to saved files in the rt sub-directories. DSH
  760 12/15/07 VA E 1 Move all options documentation from User Guide by program to new z390 Options web page which lists all options and which programs they affect.  This web page also includes java execution options, environment variable options, and file types. AK
  790 01/16/08 VA P 1 Correct az390  assembler as follows:
1) Set DFP constant exponent to match decimal point similar to P.
2) Correct exponent bias for ED and LD (was using DD bias in error)

1.  Wrap options to 80.
2.  Change default to NOSTATS.
3.  If option STATS or STATS(file) is specified, direct all statistics to the statistics file rather than to BAL, PRN, LST, and LOG files.
4.  List all changed options on STA file.
5.  List all macro/copybook file cross reference on STA file.
6) Add ECHO OFF to all batch commands such as ASMLG.BAT to suppress output listing of BAT file commands.
7) Echo start and stop messages on console and ERR file regardless of CON setting and include z390 and J2SE version on start message.
8) Only put copyright and license msgs on PRN, LST, and LOG files.
9) Change the command files ASMLG.BAT, ASML.BAT, ASM.BAT, LINK.BAT, and EXEC.BAT to set ECHO OFF so the only messages appearing on the GUI or command line log display are the START and STOP messages if CON option is off.		 AK
  756 12/09/07 VA P 1 1)  Fix all file parameters to accept relative or explicit path for file including paths with double quotes if needed, and paths starting with drive and no explicit path (i.e. relative path on specified drive.
2)  Fix GUI file selection to not include 2 sets of double quotes for paths with spaces.
3)  Fix @file processing to handle parms with spaces in "...".
4)  Fix file processing to issue error on unrecognized file name formats such as one ending with dot.  		AK/PJF
