I realized that the first time I ran it.  My terminal quit. :)  I  
haven't looked into this, but I imagine shell  functions support some  
kind of 'return' value instead of 'exit'?

Thanks to all who have responded.  The programming isn't hard, but  
the shell environment is a little different from things I'm used to  
developing (web apps w/ PHP mostly).  It underscores the fact that  
understanding the context a program will run in is critical.
