There is an ongoing discussion on the CICS-L list about doing a STORAGE macro or GETMAIN/FREEMAIN. Some are saying that these functions can result in a "wait" for the CICS QR TCB (the TCB under which most of the CICS transactions are run). The discussion has now become that the STORAGE macro issues a PC, which does an implicit "wait". My opinion has been that a normal STORAGE function does not do a ss-PC or cause the TCB to wait. It may take some CPU and cause response time problems, but the z/OS TCB does not go into a WAIT or SUSPEND state (non-dispatchable).
Anybody have a definate response as to whether a STORAGE function can cause the TCB to become z/OS non-dispatchable. I agree that it is not a good idea to do this in CICS.
