Changing User Capabilities from MPE
User Defined Commands (UDCs) combine sequences of MPE commands into a
single procedure. This means that you can type one UDC name to execute
several MPE commands. The HP Desk operator commands are examples of
UDCs, as is the command HPDESK. When a user types HPDESK, they are
actually calling a UDC, which issues the following MPE command string:
:RUN HPMAIL.HPMAIL.SYS;LIB=G;PARM=0;INFO=""
In certain circumstances, you may decide to edit the UDC provided with HP
Desk. Below are some examples of where this may be useful:
* To include the option NOBREAK in the HPDESK UDC. This would
prevent users from gaining access to MPE from HP Desk using the
Break key. (Even if users are configured without MPE access, they
could otherwise still reach MPE in this way, and then RESUME back
into HP Desk.)
* To cause HP Desk to save the terminal's function key set when it
is run, and to restore it on exit. This is done by editing the
HPDESK UDC to set the Job Control Word (JCW) SAVESOFTKEYS to equal
1.
Further information on all aspects of UDCs is provided in the MPE
reference manuals.
