Running applications in the link pack area

Programs written in assembler language, C, COBOL, or PL/I , can reside in the link pack area (LPA). To do so, they must be read-only and have been link-edited with the RENT and REFR options. Other requirements are as follows:

Assembler
Use the RENT assembler option.
C
Use the RENT compiler option.
COBOL
Do not overwrite WORKING STORAGE. (The CICS® translator generates a CBL statement with the required compiler RENT option (unless you specify the translator option NOCBLCARD).
PL/I
Do not overwrite STATIC storage. (The CICS translator inserts the required REENTRANT option into the PROCEDURE statement.)

If you want CICS to use modules that you have written to these standards, and installed in the LPA, specify USELPACOPY(YES) on the program resource definitions in the CSD.

For information about installing CICS modules in the LPA, see the CICS Transaction Server for z/OS® Installation Guide.
