AREV COMMON for a Collector window (AREV32)

Hello AREV32 fans,
My issue centres around the WCHANGE Common variable.
I make a change to data at a prompt in the Collector window (and confirmed that WCHANGE=1), but when I press <F9> and back to my subroutine via the "Save" hook on the Collector window, WCHANGE=0.
What happened?
The window is initiated by a program. There are various hooks in the window that make calls to a subroutine. I would have thought that the Window common would still be "active" since the call to the subroutine is explicitly done from that window.
I want to write data from the Collector window to a file with a generated key, but only want to write this if there has been a change to the data in that window. Is there some other hook to use? Another way to check for changes?
Robert.

Hi all,
My mistake.
Having read the utility_doc item for AREV.COMMON and for "WCHANGE", I see that this relates to a prompt, not whether there has been a change to the Window. Some confusion based on the name of this Common variable.
I have since set OREC based on the choice made from a popup of records, and then check whether data has changed between this and @RECORD (actually I only check 2 specific fields for changes).
Robert.
