How to Avoid (Con’t from page 4)
In our own applications, the File Exit command performs a certain amount
of cleaning up before it issues its CLEAR EVENTS. Specifically, it iterates
through the collection of open forms (that is, the Forms collection in
SCREEN), closing each form in turn. As it does so, it prompts the user to
deal with any unsaved edits. At that point, the user can decide to cancel
the shut-down, in which case the exit routine will leave the relevant form
open and refrain from clearing the event loop.

The application needs to go through this same procedure no matter how the
user tries to close down. To achieve this, we put the above processing in a
procedure, which we call FileExit. The Exit command on the File menu
calls this procedure with a simple DO FileExit. And so does the ON
SHUTDOWN command. In other words, instead of executing ON SHUT-
DOWN CLEAR EVENTS, we execute ON SHUTDOWN DO FileExit. That
way, the shut-down procedure is always the same, whatever the user did to
initiate it.
