LINKAGE

The CICS preprocessor LINKAGE option enables you to control whether or not the preprocessor inserts the DFHEIBLK and COMMAREA into a program's Linkage Section and updates the USING clause of the PROCEDURE DIVISION header
LINKAGE=NO

You can shorten LINKAGE to LINK, YES to Y and NO to N.

For example, /CICSECM(LINKAGE=NO).
