System 36 internal display file....ARGASOFT.....

ARGASOFT ... the messages are program, not system... very simple program, I 
am missing something so simple I am sure... This is a <snip> of the screen in 
question.... MCODE and CZPN are initially displayed blank. User keys batch 
number and date... press ENTER... screen 6 displays with MCODE, part, etc. 
User enters data, press enter... MCODE is blank immediately...

The above lines display screen 6, you enter data, press enter, and do an F11 
on MCODE in debug, and it is blank Immediately after above lines. It is 
somehow clearing it immediately after I press enter... but I just don't see 
what could clear it....
