I am stuck with the following problem and I think that I am
overlooking something. Part one of my problem was rather easy,
problem is really with part 2.  Here it comes:

 1. I needed to "synchronize" the running of several processes. Those
processes were SPAWNed from different accounts IN THE SAME GROUP. It
was easy enough to create a (temporary) event flag cluster that all
these processes shared and make 'em all wait for a specific event
flag.  I did this using two very simple programs that I called WAIT
and SIGNAL. Essentially when SIGNAL is run, the WAIT program quits
running (the event flag is set). 
 2. What I need to do is the following:
    I need to declare an AST routine in a program. The AST routine
should be called when (preferably) an event flag is set. Problem is I
could not find a way to let the  program run - apparently you must
WAIT for the event flag to be set. I need to let the program run and
be interrupted by an event flag being set. 

 Any of you Gurus out there think this is childlessly easy ?
 Thanks a lot ...
