ILBOCT1

ILBOCT1 is a COBOL library routine that is invoked by the COUNT compiler option. ILBOCT1 lists each COBOL verb, its statement number, and the number of times the verb is executed. You can use these frequency statistics to ensure that all parts of a program are executed during testing, and to determine which parts of the program are used heavily.

Hints

ILBOCT1 is used mainly for testing and debugging. If ILBOCT1 has high CPU consumption, and your program runs in a stable environment where frequency statistics are not necessary, you can reduce CPU by turning off the COUNT compiler option.
