It is also possible to use the Command table to disable an existing tablesONLINE command. This is useful if you wish to prevent users from issuing certain sensitive commands such as CICS.
Note:
The Clear key is equivalent to entering either
CICS or X on the command line. To disable the CICS command (<Clear> key), add a row with the command alias set to CICS, the actual Command field set to END and the other fields cleared. Now if users try to use leave tablesONLINE by using the <Clear> key or the CICS line command, they will simply be returned to the previous screen. Remember to remove the row with the command alias X to prevent users from accomplishing the same function using this command alias.
