Hallo Monks...

It would be convenient for me to be able to interrupt a Perl script by pressing some key, which would pause execution and let me modify a few variable via a subroutine, and then resume execution... that is, pass in parameters on the fly, like a 'mainloop' would allow for a GUI system.

All the simple ways I can think of to do this are pretty kludgy (i.e. a seperate script that modifies a file that gets periodically checked, etc.). Would pipes be involved?

Ideally I would like to avoid forks... I could make a forking system work for my application, but it would be overkill and wouldn't generalize well.

Anybody have suggestions? Simpler is always better!

Thanks
