****************************************************************
Comparing with previous Enterprise COBOL programs, COBOL V5
dynamic calls consume a slightly higher CPU time when running
under CICS with the CBLPSHPOP option set to OFF.

    



Problem conclusion


    

  • COBOL library dynamic call routine has been improved to avoid an
overhead when CBLPSHPOP option is set to OFF.
