What is the difference between INCLUDE and JCLLIB? Are not they just same?

There are not enough post in the Forum yet to search, however, this is pretty straight forward question. Have you tried with manuals?

I'll try to come back with some answer if you don't get it.

Good Luck!

In simple words - an INCLUDE in JCL is analogous to a COPYBOOK in a in COBOL. It allows you to write "lines of repetitive code" once and use it many times and in many places throughout your JCL.

JCLLIB is analogous to a JOBLIB. Instead of pointing to an alternative load library that remains active for the length of the JOB, a JCLLIB statement points to a JCL library to be used for the length of the JOB. All cataloged procedures referenced in a JOB are searched for in the JOB's JCLLIB. If a JCLLIB isn't provided, the default JCL library is searched.

Personally I've used so many times to test PROCs before they're moved to production.

Thanks Anuj.

You're welcome.

If a JCLLIB isn't provided, the default JCL library is searched.

The default JCL library sequence is defined in JES (JES2 or JES3) and the best source of information about the libraries included would be the site support group since each site may (almoist certainly) have different libraries listed.
