Simple example - Break FOR loop inside an event structure based on Front panel event change.

I'm afraid of your design (seems like you're making it way too complicated), but the following snapshot shows how to stop a FOR loop prematurely (or a WHILE loop) that is inside a consumer loop.  This should stop your loop based on a new event (all your events must generate a new queue element for this to work - INCLUDING the STOP button in this case because otherwise your consumer loop will never know that a user has clicked on the stop button.)

Please design carefully.

1. Yes the complexity of the program is increasing. But what other way can I use to run something like a stepper motor for N times.  The FOR loop (or While loop) is the easiest.

2. Producer/Consumer architecture took slighlty longer time than just doing it with event structure. Is there a reason for this or is it just because it is parallel loops architecture.
