JOBLIB DD statement

Purpose: Use the JOBLIB DD statement to:

Create a private library.
Identify a private library that the system is to search for the program named in each EXEC statement PGM parameter in the job. Only if the system does not find the program in the private library, does it search the system libraries.

A private library is a partitioned data set or partitioned data set extended on a direct access device. Each member is an executable, user-written program.
