Cobol Enterprise-Compiler for z/OS

[schmetterling]

Dear Forum,

we want to introduce the Cobol Enterprise-Compiler for z/OS.
Parallel we use PLI (LE), C, C++ and Assembler.
Have you any experiences, tipps etc ?

Thanks a lot !!

What compiler are you moving from (or are you just introducing COBOL to an existing PL/I environment)?

Do you already use LE as the *only* run-time and link-edit library (or are you still using VS COBOL II or OS/VS COBOL run-times).

Are you using IMS? DB2? CICS? Other sub-systems?

Depending on your answers to some of these, I (we) might be able to give you some guidance.

Hello Bill,

here the answer: now we use cobol LE, CICS, DB2 V7, IMS and VSAM.

Best regards !!

I don't know what you mean by "COBOL LE" - but if you are currently using the LE run-time library with any previous COBOL compiler, you shouldn't have many (any?) problems.

If you are moving your source code, IBM recommends that you do NOT do a "mass re-compile" - but simply use the new compiler for new development and for when you are doing maintainance.

You certainly should read (or at least know what is covered) in the Migration Guide at:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IGY3MG20/CCONTENTS

Known major (and semi-major) issues:

1) A few new reserved words

2) Not supported on VM (not a problem for you)

3) Totally new (revised) OO support (not a problem for most shops)

4) Removal of CMPR2 support (you shouldn't have been using this for many programs - but some shops were)

***

Of course, you also need to check with your 3rd party vendors to make certain that you are on a release of their products that support Enterprise COBOL (Check out products like Xpediter or Intertest, Abend-Aid, DumpMaster, etc)

Finally, If you are ALSO doing an Operating System upgrade at the same time, make certain that you check your default LE run-time options.

Perhaps you also want to convert PL/I to COBOL?
