On *nix boxes, you can put an appropriate ``trap'' statement in the
wrapper
that start's FilePro.  This should do the trick someplace in the script
before it fires off the real FilePro binary.

trap '' 1 2 3 15

I first ran into this with RMCOBOL on Tandy Model 16s where breaking out
of
the program leaving the ISAM files in a mess.

That might not take care of the total nuking of a session when Windows
crashes.  I doubt that wrapping in ``nohup'' would help there.  In a
database with transaction rollback, one could probably handle this by
catching the signal, and rolling back all transactions before exiting.



Bill,

I've got trap "" 1 2 3 in /etc/profile.  Should that not be enough?  I
don't see how this prevents the user from clicking on "X" & quiting the
telnet program while they are still posting.  

I put trap "" 1 2 3 15 in my .profile and tried a posting routine.  I
clicked on the "X" on Anzio & I it exited.  My posting routine aborted &
was screwed up.  Since no one else answered, maybe there is not solution
to this other than training users not to do it.  That's a pretty poor
solution.

Regards,

Scott
