In a flat sequence how do I put in a control to go to a specific frame?

[Star_Man]

I am trying to build a flat sequence with several frames (3 to 5).  Each frame will conduct a unique activity.  As the program is running I would like to be able to return to a specific frame and start the sequence over again.  How do I put in a control that will allow the user to return to the wanted frame and start the sequence over again?

You can't. The sequence structure is not designed to do this and there's seldom any reason to use a sequence structure in the first place. What you need to do is implement a state machine architecture. Basically a case statement inside a while loop with the case selector wired to a number, queue, or enum that determines the next state to execute. There are a couple of shipping examples and additional ones to be found if you do a search of NI Dev. Zone.

I agree with Dennis in that a state machine is the best way to do this.  Alternatively, a dirty way of doing it is to use a For or While loop to enclose just those cases you want repeated.

Here is a simple example of a state machine that repeats certain states (like repeating frames) until a certain condition happens, then it exits.

Grretings every body,

 tbob  .. Would you please give me a VI example of state machine in LabView 7 (not 7.1)

Thanks

Many thanks LV_Pro.
