FORMS, detecting modes, etc

In Oracle forms (10GR2, though I doubt that makes much difference).

I am trying to find how to do the following, feedback appreciated.

A form can be in POST ONLY mode. (COMMIT not allowed).

        Q: how can a form detect it is in POST ONLY mode?

A form can be in QUERY ONLY mode.

        Q: how can a form detect it is in t QUERY ONLY mode?

EXIT_FORM can prompt a user to "SAVE CHANGES?"

        Q: is there a way to control the text of the question?

	(Not the message afterwards that says "records saved", just the
	 string used as the question text.  The message afterwards is
	 seen by ON-MESSAGE/ON-ERROR triggers.)

Feedback appreciated, thanks. Received on Fri Aug 01 2008 - 13:29:35 CDT
