procesing problem

[Robert Pulliam M.D.]

    unix and filepro

    running @keyu processing in file named ASappts
@keyu    if: 
    then: system call
    if: 
then: look appts = ASappts2 r = nn -n
    if:
  then:  copyin appts;delete appts
    if:
  then: display;write
    if:
  then: pushkey "[save][save]";end
    if:      
then: return

Running the debugger everying works fine thru display with all data correct.  When puskey is executed the record is deleted or data is removed and I am returned to the record with options at bottom of screen but blank data!  The exact same processing run on a DOS based machine works perfectly.   Help
