Cataloged procedures are invoked through a specification of the name of the procedure over the Exec statement and cataloged on the library of the procedure. For verifying a procedure PRIOR to becoming a catalog procedure we will use an in-stream procedure. Instream procedures are similar to catalog procedures but there is a small difference at their EXECUTION:for executing them there are required to be PLACED between the JOB statement and the Exec statement and they MUST be finished with a Pend statement.
