IGZCLNK

IGZCLNK is the COBOL linkage manager routine. It provides run-time support for the CALL and CANCEL verbs. The CALL statement transfers control from one separately compiled program to another. The CANCEL verb releases storage occupied by a called subprogram.

This routine is only called when the DYNAM compile option is used.

Hints

CPU execution in IGZCLNK indicates use of dynamic CALL and possibly CANCEL verbs. Subprograms can be called either dynamically or statically. Static calls are quicker because the programs are linked at link-edit time.
