The END–ERROR Key
The END–ERROR key (usually F4 in a character interface, and ESCAPE on Windows in graphical interfaces) is so called because sometimes Progress treats it as ERROR and other times treats it as ENDKEY:
This code runs the following procedure:
![]()
At this point, you are at the PROMPT–FOR statement in the procedure. Press END–ERROR. The procedure returns you to the Procedure Editor. Run the procedure again, entering a 1 for Cust num and press GO:
![]()
At this point you are at the UPDATE statement in the procedure. Press END–ERROR. The procedure returns you to the PROMPT–FOR statement and lets you enter another customer number.
