DOH! I cannot believe that that was all I had to do. What is the 
difference between 'ouput' and './output' if I am trying to run to 
program from the directory it resides in. In other words, if I am in 
the directory where the compiled program is when I try to run it, why 
would it need to be in my path??

Actually it didn't help, neither did the gcc HOW-TO. You certainly 
did though. Thank-you for the reply. I imagine I need to do the same 
thing at the office under HP-UX.
