Error description
At OPT(1/2), a level 88 item with thousands of entries defined as PIC 9 can lead to excessive zoned comparisons resulting in a performance degradation.

Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V5.2 compiling * * programs with packed-decimal data items * * with a large amount of level 88 values. * **************************************************************** * PROBLEM DESCRIPTION: An IF clause checking a level 88 data * * item with a large amount of values * * causes the compiler to generate a * * large internal representation of the * * program which causes compilation time * * to increase. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** A level 88 check expands into IF statements on each level 88 value. A very large amount of level 88 values generates a very large amount of IF statements which generates very large internal representation of the program.
Problem conclusion
The internal representation of level 88 checks for packed-decimal types was compacted to simplify the program's internal representation.
