You can define your own commands for use with the TPF system using the ZFMSG command. For example, you can define commands that call or end user exits. You can also define your own command table (UMET) and command editor programs without impacting TPF commands.
The TPF system does not release commands that have a secondary action code of U; for example, ZUxxx. These commands are reserved for you, although you are not restricted to ZUxxx.
All the commands that you create are passed to the UME1 program segment. UME1 displays the following message when it receives control and causes the ECB to exit without performing any processing:
UME10000I NO USER COMMAND EDITOR AVAILABLE FOR ZUxxx OR ZDIAG COMMAND--ECB EXITED
