Subject: Re: chomp - works in irb, not in program

Douglas:
I forgot to mention that the puts command outputs the prompt to the 
screen, but the program never pauses to give the user a chance to enter 
anything for an answer.  I'm assuming that's why the .chomp part doesn't 
work.  The first thing I need to do is figure out why gets isn't causing 
the program to pause to accept the user input.
Thanks,
PV
