MyIndicatorAction

Here's how to declare an action procedure for an indicator if you were to name the procedure MyIndicatorAction:

PROCEDURE MyIndicatorAction;

DESCRIPTION

Your procedure can perform any action appropriate for the control part. For example, if your application plays music while displaying a volume control slider, your application should change the volume in response to the user's action in the slider switch.
