A procedure library is a program library that stores JCL that is used repeatedly. These standard JCL statements reside in these procedure libraries and are referred to as procedures (or procs). Generally, each procedure uses the symbolic substitution feature of JCL to allow modification of specific values in the stored procedure before the procedure is submitted as a job. JES2 accesses the JCL stored under the procedure library (proclib) member and merges it with the submitted JCL. This merged JCL is then placed in the appropriate job queue for execution.
The JES2 Proclib Display shows you the names of the JES2 procedure libraries on the system and tells you whether an operator is permitted to modify these libraries. This screen follows with sample data.
This display uses the JES2 procedure in SYS1.PROCLIB to find the procedure libraries that JES2 uses. The JES2 procedure might have been changed after JES2 was started. In that case, the proclibs indicated by the display might not be those that JES2 is using. Review the appropriate sections in the Usage Guide for more information about JES2.
