CA Compress/2 › Using CA Compress/2 Under CICS › Install the Callable SHRINK Subroutines for CICS › Step 4. Modify and Link edit the Application Programs

Step 4. Modify and Link edit the Application Programs

You must convert your application programs to call the SHRINK and EXPAND subroutines correctly and link edit them with the SHRKCICS module. If you are converting from the Macro Level facility, which is not supported under CICS Version 3, you must not mix this Command Level facility with any modules, including SHRKCICS, from the Macro Level facility. Convert the application modules as follows:

• If you are converting existing application programs from the macro-level product that was supplied with releases of CA Compress before version 4.6.3, you must change the programs as described in the comments in member INSTALL. In particular, the call to SHRKCICS must conform to command level specifications:
  • Register 13 must point to a valid save area.
  • The 5 arguments required by CA Compress must be preceded by the EIB and a dummy DFHCOMMAREA.
• Link edit the application programs with the SHRKCICS module for CICS. Do not use SHRKSTUB, SHRKEXPD or the Macro Level version of SHRKCICS.
• Define the application programs in the PPT as usual.
