Thanks very much Tim, that was just the ticket! Unfortunately I now
realise that the tailbox may not be what I need. I want the script to
start the compilation but carry on when it is finished whithout the
user having to press <Exit>. Do you have any suggestions how I can
compile the program and inform the user that this is happening (either
through showing the compiler output or not - they dont need to see the
output as they wont understand it anyway, it was just a way i thought
of so they dont think it has stalled) but then carry on with the
script to bring up the next box afterwards.
I have attached my script so far in case others find it useful (and so
you know im not just freeloading and getting others to do it ;) )
