Date: | Sun, 22 Feb 2009 06:11:22 -0600 |
For any
of you who might be interested and who didn't see yesterday's announcement
regarding zCOBOL, see below.
FYI,
Unlike COBOL-IT, this is NOT a "derivative" from OpenCOBOL and actually is
targeted at a (basically) different audience than OpenCOBOL.
If you
come from and/or are familiar with the IBM mainframe (especially IBM mainframe
assembler) environment, I think you may find the SHARE presentation foils
interesting. From the links provided below, see:
NOTE: If you do NOT know the IBM mainframe or assembler
environment, you will probably find much of that presentation as "baffling" as I
do snippets of C/C++ and UNIX/Linux stuff in OpenCOBOL

and zcobol full release v1.5.00 now available for download via www.z390.org with
zcobol and z/CICS V7. For details on RPI fixes and enhancements in this
full release visit: http://www.z390.org/z390_Download_Archive.htm
The
major enhancements in this release which have been in development for almost a
year now include: 1.
zcobol
open source portable mainframe COBOL compiler which produces HLASM compatible
executable source and object code which can be run on z9, z10, or z390 on any
J2SE platform including Windows and Linux. For documentation on zcobol
including demos, regression tests, and initial NIST ANSI 1985 COBOL test suite
results visit www.zcobol.org. 2.
z/CICS
V7 EXEC CICS support for COBOL and assembler contributed by Melvyn Maltz.
For the latest documentation on this release which includes EXEC CICS COBOL demo
programs visit: http://www.z390.org/z390_EXEC_CICS_Compatible_Assembler_Support.htm
Additional
fixes and enhancements in this full release
include: 1.
Correct
mz390 _expression_ parser to convert substring _expression_ with single SETA
variable to SETC string. 2.
Correct
mz390 and az390 to set &SYSLOC to private CSECT name when EQU or USING is
used prior to first CSECT. 3.
Correct
az390 to use higher numbered base register when 2 base registers
coincide. 4.
Correct
az390 to handle negative displacements for LA instruction when there is a
depending USING register with displacement large
enough. 5.
Correct
SAVE macro to use 13 instead of 0 when ending register higher than starting
register. 6.
Correct
az390 to handle mixed case labels on labeled USING and
DROP. 7.
Correct
az390 _expression_ parser to allow unary minus before length operator and allow
labeled using for absolute symbols even though they are not
required. 8.
Allow
az390 to resolve relative offsets across CSECT’s if option ALLOW
specified. 9.
Increase
MZ390.BAT macro processor minimum memory allocation to 150 MB to reduce garbage
collection cycles and increase speed of zcobol macro processing (the minimum
memory required is about 80 MB. With this setting over 300 NIST compiles
completed in 25 minutes). 10.
Optimize
the XC instruction when used to zero area of memory to avoid multiple fetch and
store loop. 11.
Add
the following new options COMMENT, EXTEND, R64, TRUNC, and WARN for use by
zcobol. For an interesting read compare the zcobol\test\TESTTRC3.CBL code
generated and executed when using TRUNC which generates LG and DSG versus TRUNC
NOR64 which calls zcobol\z390\ZC390NUC.MLC runtime library routine to perform
truncation using DXR to avoid changing 64 bit GPR registers (I think it’s faster
than Enterprise COBOL’s routine using multiple CVD, DP, CVB,
etc.) 12.
Add
support for the following DCBD fields DCBEODA, DCBRECF, DCBRECBR, and DCBRECU
even though undefined record format is not currently supported by
z390. 13.
Support
list and execute forms of WTOR in addition to standard
form. 14.
Add
new CPOOL macro to support BUILD and GET functions for fast access to memory
quick cells avoiding GETMAIN overhead on every
request. This
release has been regression tested using J2SE 1.6 update 12. I hope those
of you interested in the new zcobol addition will join the zcobol user group for
discussion of COBOL bugs, fixes, enhancements, and future direction. This
first release of zcobol should be considered a beta test version as more work is
needed to get zcobol to pass all the NIST ANSI COBOL 85 tests. But it does run
the demos, regression tests, and the EXEC CICS COBOL programs
included. The
current plan is to continue publishing z390 and zcobol as single releases and
PTF’s and the support log will contain both types of RPI’s. For the
pending zcobol RPI’s which start with 1001,
visit: http://www.z390.org/z390_Support_Request_Log.htm
I
am really glad to get this release out the door in time for SHARE although it’s
a little painful not having time to get as much of the basic functions done as
required to get most of the NIST tests running yet. The next z390 v1500a
PTF should be better. I hope this tool catches on as an educational tool
and as a useful legacy modernization tool. If any of you all would like to
join in the development effort let me know. In addition to the COBOL to
HLASM option, there is also a zcobol option to generate native java, C, or Intel
assembler and there are commands included to run the zcobol\demo\HELLO.CBL demo
on all 4 target language environments. But there is a lot of work to do to
develop these options further and my current priority is focused on the COBOL to
HLASM option. All
suggestions, comments, bug reports, and enhancement requests are welcome.
