I have disabled TPXOPER display and update of memory so why can the user still display memory usage information, for example STOR and STORXA?

Resolution

Storage and memory are not the same things.

DISPLAY MEMORY (D MEM) can display memory within the region.

DISPLAY STORAGE (D STOR, D STORXA) can display information about the storage being used by CA-TPX. The product allocates storage from the following storage pools:

• The Dynamic Storage Area (DSA) for areas that are large or highly variable in size.
• A series of fixed-length slot pools for small or fixed-length areas.

Access to Operator Display commands are all or nothing, except for MEM. Since you can display and modify memory (D MEM,ACT=actentry) which would effect how TPX runs and could cause an abend, TPX provides the additional level of control explicitly for D MEM commands.

Unless you restrict DISPLAY entirely (N - DISPLAY - Display Information), you can't stop someone from displaying STORAGE (which is NOT memory). You can stop them from displaying or modifying memory by setting the display and/or update memory option to N.
