Well, there pieces that you have not intimated.

1) if it's field 99 you are leaving are you using @wlf99 in the label 
section of the processing table? It doesn't work on the If: section.

2) what processing table is the code in? Are you sure you are calling 
what you think you are from the menu?

input.prc


1 --------------------
           if: 'good idea to end first. No need for table after SAVE
         then: end
2 --------------------
@wlf99   if:
        then: show "@Leaving Field 99"
3 --------------------
          if: 'your lookup
        then: lookup foo=bar ...
4 --------------------
          if: foo
        then: x=foo(2);display
5 --------------------
          if:
        then: end
-----------------------

3) are you sure you haven't just dcabe'd the processing table, and you 
are running rclerk?

3a) what's the menu line that is running the code?
