Hallo *,

I like to parse PO datasets containing JCL and like to retrieve lists with found datasets, programs etc. which are involved in the JCL.

Background: JCL should be deleted, including dependand datasets, programs, DB2 plans etc. on the JCL which should be deleted.

Does anybody know, if some kind of parser for JCL is available?

Thank you for any helpful hints,

kind regards
bauer

bauer,

A simple SUPERC in batch for DSN= and PGM= will give you the list of the datasets and programs, however, it wouldn't be able to find which datasets needs to be deleted.

Also unless you have instream control cards (for DB2 plans or for that matter any program that uses IKJEFTxx), we wouldn't be able to find the plan/program names

Hallo Kolusu,

thank you for your answer.

Yes, you are right - program invocation by IKJIFT01 with ISPSTART PGM ....., PROGRAM (....) PLAN (....) does noz work with any simple search.

Thus: We wrote a small PL/1 program including the topic "check for other usage" of potential DSN, PGM which are candidates to be deleted.

Thank you again, for your time to answer this question,

kind regards,
bauer
