break points or restarting a program

[Kasey]

I was wondering if there is a way to restart a LabView program.  I found vi's for Stop and Exit, but nothing to restart.  Or, is there anything equivalent to a breakpoint, so that I could go back to an earlier state of my program.  I have an error polling loop and when I find an error I want to display an error message and then go back to the start up state of my program.  I don't want to have to exit the program and open it up...I'd like it to happen automatically.

Thanks,
Kasey

It's called a state machine architecture. Simply put, a state machine is a while loop around a case statement. You can have a shift register in the while loop wired to the case selector and in each case, write a value to the shift register to determine which case to execute next. Another way is to use a queue. In each case, you enqueue an new value and a dequeue function is wired to the case selector. There are shipping examples of both (State Machine Test Sequencer, Queued Message Handler, Old Event Handler).

You could put the whole thing in a while loop and wire the error to the stop/continue control.  A lot of people use while loops when they want a breakpoint of some sort.

*Edit: Dennis described it much better than I could.*
