ILBONTR

ILBONTR is a COBOL library routine that loads and deletes COBOL subroutines. ILBONTR loads the COBOL routines that are not yet loaded into the region, and deletes those routines that are not called by any other program in the region. ILBONTR is called:

  • When the RESIDENT option is in effect

  • When the DYNAM option is in effect

  • While processing a dynamic CALL or CANCEL statement

Hints

CPU execution in ILBONTR 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.
