This message would be issued if you were in TPXOPER trying to enter a command that you are not permitted to do. This example solution will show you how to allow users to issue DISPLAY commands in TPXOPER.
You should see a screen like this:
TPX Operator Command Class Table: NEWGROUP TPX Operator Command Class: D Y - ACTIVATE - Activate application Y - QUIESCE - Quiesce applications Y - CANCEL - Cancel user/sessions N - RELOAD - Reload panels or tables Y - DISPLAY - Display Information N - SEND - Send messages (all but memory) Y - SPIN - Spinoff TPX Log Y - MODIFY - User ONLY Y - TRACE - Trace on/off N - MODIFY - All operands N - UNLOCK - Unlock terminals N - MEMORY - Display memory N - MEMORY - Update memory Y - VTADD - Add virtual terminals
On the left hand side you can see DISPLAY is Y. This allows you use DISPLAY commands in TPXOPER. If the value is "N", change it and RELOAD OCMD=tblname in TPXOPER. For the above example that would be RELOAD OCMD=NEWGROUP.
