I would like to thank Rob Peck for providing a workable solution to my
orginal question about having a script wait for completion of an event or
multiple events.  Instead of using a file as a signal and having the parent
script do a wait-loop I used a pipe as a kind of semaphore.  The parent
script once it has started the others as background tasks does a type pipe:a
(or whatever pipe name desginated).  This causes the parent to halt until
somebody writes to that pipe.  
 
One question I do have about this method: does the Amiga OS waste any CPU
resources while that script is trying to read the pipe?

Thanks again Rob for the quick reply.
