Howdy, David!

What you may want to do is scan the keyboard buffer at some point in each
loop and make sure the user hasn't mashed a button.  For instance, you could
do this ...

procedure killProggieNow()

    -- Did the user press a key?  If not, exit the procedure.
    if get_key() = -1 then
        return
    end if

    -- User must have pressed a key.  Do stuff to shut down program nicely
    abort(0)

end procedure

And then, somewhere in each of the loops, put in a call to the above
function.  If you've only got a couple of loops to monitor, then it would be
better to just insert the function's code into the loop (inlining it), as it
would make your program run a tad faster.

Hope this helps a little, anyway ...
