Users needed a field added to the item master to track an atrribute of that 
item. They needed it ASAP (At least they thought so). I knew which programs 
updated (add/change) and which ones just used it. I did exactly what Art did. 
Recompiling all of the programs, moving to another system and installing would 
have been a huge drain on resources. Although I did recompile and install all 
of them on the following weekend.
