VI of the Day (8/16/09)

[Darin.K]

A structure for today "Stacked Sequence Structure"  Quick-drop or drop-kick?

 I'll admit to using a few of these...In LV2.  Still a few kinks in the whole left-to-right thing back then, plus they hadn't really adopted the error cluster and other pass-through methods of flow control.  What's your excuse today?

If you don't like the rampant parallelism in LV and like to have a cup of coffee while your VI runs, then this is for you.

I still have found one use for these, I can hide any Express VIs that I happen to use on a BD.  A case structure with a constant wired is also effective for this, but a little more obvious to those looking over your shoulder.  In that case, use a hidden control wired to the case structure... 

Joking aside, read the section on avoiding these, some of the best advice in the help.

I've found the ONLY reason people tend to use sequence structures is to put 'Wait' functions between certain operations.
You can use the wait from OpenG.
This way, you can just wire the error cluster through, and save yourself all those frames.

As I mentioned in the Stacked Seq Eleimination Nugget , the Stacked Seq Structures are great place to put your design docs!

By imbedding the design doc in the code, those that follow in your foot steps can easily tap into the design with a click or two.

I tend to drop-kick them but I'm a bit of a snob.  They still have a place on the palettes but are often misused and abused.  I usually right click a stacked sequence and convert it to a case statement.  A state machine is just moments away.

That would be theonly use for them..  Because of their abuse, they should be banned from the structures palette....

Or, if not banned, at least moved to an "Advanced" subpalette.  Beginners would not look there and be much less likely to use and abuse them.

I just need to remember to start using Ben's suggestion.
