What is JOBLIB and STEPLIB in JCL? what is the purpose of
using it?

Answer Posted / sai

Both joblib and steplib for specifying where loadmodule is
located. I.e address of loadmodule dsn. But here big
difference between joblib and steplib is IF you give
loadmodule address in joblib it assigns to all steps in one
jcl. I.e for all steps takes this loadmodule address.

In steplib: loadmodule for that step only.i.e takes
address of loadmodule for that step only.

and if you give both steplib, joblib, For each step steplib
address overrides joblib address.
