Re: Keyboard input time out routine

Thanks Matthew, I was able to expand your information to get a working idea of
what to do.  Looks like I need to write a procedure (like I did in C++ using
kbhit and getch) to process any keystrokes and build the number, and time out if
the enter key is not hit in the allotted time.
