Happens when some event happens other than the standard events that REXX GUI supports, and for which REXX GUI has specific event handlers.


Args

ARG(1) is whatever the "WPARAM" arg is for that event. What it's purpose is depends upon what event has happened.

ARG(2) is whatever the "LPARAM" arg is for that event. What it's purpose is depends upon what event has happened.

ARG(3) is the "message number" for the event.


Return

What you return depends upon the event. Some events may require you to return certain things.


Notes

Some add-ons, such as RexxSock, RxMidi, and RxTwain may cause events that REXX GUI does not support in its standard set of event handlers. For such events, your EXTRA event handler will be called. You'll need to consult the other documentation for details about args and returns.
