You don't need a stacked sequence structure to accomplish this. However, like the post by for(imastuck) indicates you can't simply get rid of it because it would break too much legacy code.

NO!

Don't get rid of the Stacked Sequence!

I will use a Stacked Sequence in my very often.

Frame 1 - contains all of the code.

Frame 2 - Contains an image of the State Diagram that documents the code flow. All I have to do is flip to frame 2 to see the design.

Of course if NI would restore the State Diagram Editor to its former glory I would not need the stack sequence.

Ben, I'm glad you never miss a chance for that plug.

PLUG #2!!!

Edit: I should really read all the responses first, I'll see crossrulz beat me to it. I'll add a link to another one for good measure

If it gets Jeff K on our side, I plug all day.

There is absolutely nothing wrong with the Stacked Sequence Structure. All problems stem from the abomination known as the sequence local.

Although I do not agree with your assertion about its need (you can force program flow using other methods, i.e. Flat Sequence), I do see the problems you would have with legacy code.  That's something I had not considered.

I am not familiar with FPGA; therefore, I do not see the reasoning behind using a stack sequence with it.  Perhaps someone can expand on this thought on why a Stacked Sequence would work better than a State machine if using FPGA.

Whether its a Flat sequence or a stacked sequence I would use only single frame to force the data flow :D. I forgot to state the use of this in larger code. We use to initialize the code in one frame then run the code in another frame then re-init the code in the final frame. I am not sure about the legacy code.

Yes, but you can do the same thing with a State machine.  What I am talking about are uses for a Stacked Sequence where a State machine just won't do.

[P@Anand]

Yes if my design has Init >> Execute code >> Re-init and exit do you think it is necessary to use state machine?. Because this sequence of execution is never going to change and I feel it is unnecessary to bring a state machine into play.
