Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of Enterprise COBOL V5.2 compiling     *
*                 programs with an extremely large amount of   *
*                 data items in the same group.                *
*                                                              *
****************************************************************
* PROBLEM DESCRIPTION: Compiler performance: Compiler takes a  *
*                      long time to finish compilation         *
*                                                              *

*                                                              *
****************************************************************
Data structures used to store large amount of data items in the
same group were inefficient.

    



Problem conclusion


    

  • Compiler was updated to use more efficient data structures for
large amount of data items.
