Programmatically Toggling a Boolean Control

[Anatole]

Hey,
I have a Boolean control set so that when a joystick button is pressed and released, it switches a case statement.
Since the joystick button is momentary I have it set up so:
True + False = True, then the next True+False sets it back to False. In essence, pressing & releasing the joystick button toggles the case structure.
Now, my question is, I have a sequence inside each case structure. I want to be able to toggle the case structure programmatically when the sequence is finished. (Basically, the program can run back and forth between true and false, but the user can hit the joystick button to manually override the back and forth.)
Any ideas on how I can do this?
Thanks!
