This one would work well but, if I have to stick DoOneEvent's thru the routine, I'm back to putting ->update...

I've narrowed my problem down to a few particular subroutines in particular situations and, for that, I can use fork(). Those routines only return true or false anyway so, the pipe would be simple :)

So, I guess my problem wasnt as terrible as I thought it was.

Thanks to all for the help with this. It's been a great learning experience for me! Not too sure if Tk is my cup of tea tho. Seems like a lot of work just for a user to click a button and watch the dancingteddy bear while the program does what it used to do from the command line ;)
