Problem summary

  • ****************************************************************
    * USERS AFFECTED: Enterprise COBOL V5.1 users who are          *
    *                 experiencing performance issue with          *
    *                 program working storage initialization.      *
    ****************************************************************
    * PROBLEM DESCRIPTION: When an COBOL program is executed,      *
    *                      the WORKING-STORAGE needs to be         *
    *                      allocated and initialized. The time it  *
    *                      requires to do this allocation and      *
    *                      initialization may be slower in         *
    *                      programs compiled with the Enterprise   *
    *                      COBOL V5.1 compiler. The slow down      *
    *                      may become more apparent when the       *
    *                      program is short running, and the size  *
    *                      of the WORKING-STORAGE is large.        *
    ****************************************************************
    * RECOMMENDATION: Apply provided service.                      *
    ****************************************************************
    Improve the performance of WORKING STORAGE initialization.
