Procedure or PROC in JCL

Group of JCL statements together and giving them a name is a procedure. Procedures are the pre-written segment of codes consisting of one or more JOB steps. By using procedures, the amount of JCL coding you have to do is reduced. Since it helps in minimizing duplication of code, a number of errors also reduced. Syntax: EXEC procname or EXEC PROC=procname Catalog Procedures: A cataloged procedure is a set of JCL statements that are stored as a member in a partitioned data set. Multiple jobs can invoke and use the same catalog procedure. The main reason for using catalog procedures is to avoid coding the same JCL again and again. Pend statement is optional in catalog procedure. So you do not need to code it in your JCL. Instream Procedures: The EXEC statements between the PROC and PEND statements are not executed when they are first encountered in the job stream. Instead, they are saved as a procedure to be called later. From the below example, the highlighted statements are saved as a procedure and the JOB starts executing from STEP010 step.
