All: I'm curious how Procedures are used by the systems you work on. If you have time can you answer the following questions?

1) Does you system use external procedures? Inline procedures? Do you have a few or many?

2) If your installation uses JCL Procedures how are they stored? Do you have one PROC LIB that stores all the procs?

3) If you use more than one proc lib, do you use the JCL special DD 'JCLLIB' in your JCLs to determine where the Procedures in a job should come from?


Thanks for your time!

We have several proclibs concatenated in JES2:

1) IBM distributed procs modified for our site
2) IBM procs as distributed
3) User department created procs

Some groups do use JCLLIBs.

@dick: Thanks!

@mcmillan: these aren't interview questions, I'm genuinely curious how people use these.... ???

What I'm mainly interested in is: how common is it to use JCLLIB and multiple proclibs in Jobs?

Thanks All!

Always cataloged procedures, always from just a single PROCLIB. I've never worked in a shop that allows the use of JCLLIB.
