I was going to say:  Yes, there's a way.  Push the menu button for the
program or type its name.  This will cause the program to execute before
the 48 shuts off automatically.  :-)

But seriously, your message gives me another idea.  One could turn on
vectored entry (by setting flags -62 and -63).  This will cause the
programs \GaENTER and \GbENTER to be searched for and executed at every
ENTER operation; one of those could reschedule the alarm.  It would be
easiest to use \GbENTER.  Create a program with the name \GbENTER --
that's a Greek beta character followed by ENTER.  The program should do
a DROP (to get rid of the string it is passed), delete the pending
alarm, and schedule a new one.  One annoying thing is that searching for
alarms is not completely simple -- one has to match the object in the
alarm, since other alarms may have the same time, and the index may
change if other alarms are activated or set.  Another annoying thing is
that this will consume time every time the user presses ENTER.
