IGZCDSP

IGZCDSP is the COBOL library routine that is invoked when the DISPLAY verb is used. This routine converts literals and operands to print lines. It performs any necessary data conversions. The DISPLAY verb is convenient for displaying error messages and debugging messages on the system output device.

Hints

Usually DISPLAY is used for low-volume messages. If significant CPU activity is noted for module IGZCDSP, investigate what is being displayed. Perhaps you can remove debugging messages, for example, to save time. If the displayed information is actually an output report, recoding the DISPLAY into MOVE and WRITE statements can save CPU time.
