Re: Notifying an open program(s) of a new record:

     Booth, is the subfile waiting for input, or is it just display 
     only? Just an idea off the top of my head, you might be able to use 
     a break message handling program, but not sure of any details on 
     implementation....

Either I am having a brain flat or there's more to this than meets the
eye.

I want to have a subfile program open on users' desks.  That subfile will
show selected records from a file.  During the work day records will be
added and changed in that file.  In order for the file to be up to date a
refresh has to occur.  One can of course manually refresh the subfile, or
even put a timer cycle onto it.

However there must be a way to signal the program, or at least the
workstation(s) that a change has occurred?  That seems straight forward
but it isn't clear to me.  I have been thinking a trigger on the file
would serve the purpose, and it might if I could see how to notify the
subfile program.  A second part of that problem is that there would be
more than one workstation to notify.

Any ideas?
