According to me, you should GnuCOBOL, as most of the COBOL users use it. GnuCOBOL was formerly called OpenCOBOL. It is an open-source COBOL compiler. Introduction Open Cobol ESQL (ocesql) is an open-source Embedded SQL pre-compiler and run-time library designed for COBOL applications which access an open-source database. Ocesql translates each EXEC SQL statements into the standard COBOL CALL statements to the run-time library. Cobol Compiler free download - Digital Mars C/C Compiler, IDE Cobol, Inno Setup Compiler, and many more programs. Download Product Sheet. Enterprise-Class COBOL Compiler. When COBOL applications or components are needed, trust in NetCOBOL’s development environments (Visual Studio, Eclipse or native Windows) to improve the efficiencies of your development process. Whether design, programming, testing or maintenance, the IDE conforms to your existing.

The COBOL compiler and installation files are contained in thearchive: cobol.tgz [MD5: 0ffef09764d061de8d28903d2c89a04f]. Click on the archive name to download thearchive to your computer. The archive contains:

• a HET tape image (cobol.het),

• the output of the mainframe utility TAPEMAP showing the contents of the tape image (cobol.map),

• an installation jobstream (mvtcobol.jcl), and

• an installation verification jobstream (cobtest.jcl)

• a jobstream that compiles/links/executes the 99bottles program from http://www.99-bottles-of-beer.net/ (99bottles.jcl).

Uncompress the archive (use the tar xvzf cobol.tgz command onLinux or use WinZip or ZipNAll on Windows). The tape imageshould go into your tape image subdirectory, the jobstreams should go into yourJCL subdirectory, and the map file may be viewed with a text editor or printedif you are curious about the contents of the tape image. Note: Thejobstreams were created under Windows, so each line is terminated with x'0d0a'.

The COBOL compiler consists of a set of load modules, which areinvoked during the compilation of a user written program, and a set of objectmodules, which are used during the link-editing of a compiled program. Thecompiler load modules are contained in the first dataset on the tape image (COBOL.LOAD). The object modules are contained in the second dataset on the tape image (COBOL.LIB). These two datasets were created by an IEBCOPY unload and the two libraries wereunloaded from 3350 DASD (RECFM=U,BLKSIZE=19069). The third dataset on thetape image (COBOL.PROCS) is a set of Catalogued Procedures, in IEBUPDTE format,that can be used to invoke the compiler.

Target Libraries

The load modules for the compiler must be restored to a loadlibrary and the object modules must be restored to a Partitioned Dataset thatwill be available to the Linkage Editor. The Catalogued Procedures shouldbe restored to a procedure library known to JES2 on your system. Thedefault targets in the installation jobstream are SYS2.LINKLIB (for the loadlibrary), SYS1.COBLIB (for the COBOL object library), and SYS2.PROCLIB (for theProcedure Library). If these libraries are not correct for your system,you must edit the installation jobstream before submitting it and substitutedestination libraries suitable for your configuration. Search for thecomment - <TARGET - which is contained on each line where a target libraryis named. Additionally note that SYS1.COBLIB is created in step LINK003and changes to the UNIT and VOL=SER parameters may be required to conform toyour configuration.

The installation jobstream reloads the unloaded libraries totemporary datasets and the re-links the contents to the target libraries. This allows you to place the restored modules on the type of DASD that fits yourconfiguration, rather than restrict the destination to 3350 DASD. However,you must have 3350 work space available in your configuration to restore thedatasets to during the installation.

When you have verified that the installation jobstream -mvtcobol.jcl - conforms to your configuration, mount the tape image on a tapedevice and submit the jobstream to MVS for execution. The job should takeno more than a minute to execute and the return codes expected for the stepsare:

Installation Verification Jobstream

The cobtest.jcl jobstream performs a compile, link, and executeof a simple COBOL program to print the phrase 'HELLO WORLD' on the MVSconsole. The complete JES2 output for this job may be viewed at cobtest.

After the compiler has been successfully installed and verified,you do not need to retain the installation jobstreams or the tape image on yourhost computer.

November 2004Update - I have written a macro, jobstream, and instructions for changing the installeddefault options for the COBOL compiler (without regenerating the compiler viaMVT System Generation). See: MVT COBOL CompilerDefault Options.

Patch for XREFAbend September 2019

In September 2019 there was a discussion on H390-MVS about thelong known about abend of MVT COBOL when attempting to specify XREF in theoptions to obtain a Cross Reference listing of the source program beingcompiled. Although the MVT COBOL compiler performs as expected under MVT,it always abends if XREF is requested when executing under MVS. Dave Kreissresearched and found that the compiler was attempting to organize acquiredstorage to be contiguous, which is simple under MVT, but more complex, if notimpossible, under MVS. He submitted a patch to the compiler load module thatseems to eliminate the problem and allow compiles to complete when XREF isrequested. I applied the patch on my system. In the several test compiles Isubmitted to the patched compiler, I found that XREF now provides the expectedCross Reference listing. Others posted that they had positive results when theyapplied the patch on their system. Although this does not mean that the problemis completely resolved, as very large compile jobs requesting XREF may stillabend, it seems that we can be hopeful that this has resolved the problem forthe majority of cases in the Hercules' user community.

I amproviding a copy of the jobstream here asZAPCOBOL. You may download the jobstream and run on your system to patch theload module of MVT COBOL on your system. As written, the jobstream is targetingthe load module residing in SYSC.LINKLIB, which is the library contained on myCompiler Language/Tools volume (SYSCPK). If the MVT COBOL compiler isstored in a different load library on your system, you will need to modify thejobstream to point to that library.

I hope that you have found my instructions useful. If you havequestions that I can answer to help expand upon the information I have included here, please don't hesitate to send them to me:
