POINTER usage in CICS does not differ from usage in Batch. POINTERS are used to established addressability to data, similar (in concept) to an ASSEMBLER LOAD ADDRESS (LA) instruction.

Please consult your applicable IBM COBOL Language Reference manual and review the section on POINTERS.

Note: Don't confuse POINTERS with PROCEDURE-POINTER (introduced with COBOL/370, around 15 years ago) as they are completely different.

Never use PROCEDURE-POINTER in CICS, because using it may cancel the region icon_eek.gif

Instead, use the CICS LOAD PROGRAM API command.

Hello,

At the top of the page is a link to "IBM Manuals". Among these are the COBOL Language Reference and Programming Guide for multiple versions of COBOL.

This link is to part of the pointer info in one of them:
