The Compress load library must be a PDS. Load failures can be expected if the modules are copied to a PDSE, for example:
DFS0733I IMODULE ERROR 18 LOADING COMPRESSION EXIT MODULE IMSHRINK
If you wish to run Compress for IMS as a standalone product and copy the modules to a separate load library, then this must be a PDS,
for example the IMS RESLIB. Please refer to the following Knowledge Documents which document this process.
