   Computer Nerd Kev, I thank you for your response.  The manual doesn't give any   
   information on using assembler with C.  I have the information on linking C to   
   Assembler, but it doesn't give any information on returning a value from an   
   Assembler function.     
   :(  I'm looking again in case there's something I missed.
