SYMPTOM(s):
Data appears at a field in a frame when it should be blank
CAUSE:
The application code is coded to do the following:
1) Display some variables using the DISPLAY statement with the WHEN phrase
2) Go to the next iteration of the frame using the DOWN WITH FRAME statement
3) If a certain condition is true, display a string at the located of field1 in the frame
4) Repeat with step 1, only now the data displayed in step 3 still appears
When using the conditional format of the DISPLAY statement (i.e. DISPLAY ... WHEN) if a condition for displaying a field evaluates to false then the display of the field is skipped (i.e. if the evaluation is false the DISPLAY statement does nothing with that field).
FIX:
To resolve this problem, issue a DISPLAY "" AT <field> statement to clear the data previously displayed
