No kidding. I am trying to write the data update procedure now that the add 
procedure is done, and it looks to be an even bigger pain.

Oh man, that is exactly the scenario that I am working with.  One more obstacle 
to tackle.  A major problem has been the lack of reference material for CGI as 
used with RPG. I've got a couple of books by Bradly Stone. They were good 
starting out but they don't get into the detail that I seem to need right now.  
I basically just went out and looked at various pages that used checkboxes and 
did a little reverse engineering.
