off topic:

Sounds like a complicated way of achieving this. We replaced the SIGNOFF string
in message id CPX2313 with our own command (e.g. IMDCMDE). This command
duplicated the parameters of the SIGNOFF command, but added additional options; 
0 (zero) or <command string>.
This way one could open a command line window by pressing SysRq 900, or run the
command directly by typing 90commandstring on the SysRq input line.

On V5R3 I achieve this by using an exit program (exit point 
QIBM_QCA_CHG_COMMAND )
