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 SHUTDOWN 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.
