Breaking/Indexing a Sequence structure

[Justin Goeres]

Greetings. Is there any way to "break" out of a sequence structure?
Suppose, for instance, I have a 3-frame sequence:
(1) Test a sensor.
(2) Do something.
(3) Report results.

If (1) fails, I don't want to execute (2) or (3). I can do it by having (1)
control a Case, of course, but due to the structure of what I'm doing it
would be much cleaner to be able to Break.

In a related matter, suppose I wanted to execute a Sequence beginning at a
specified frame. Is there a way to have LabView "begin executing this
Sequence at Frame #5 and continue from there?" Again, this could be done
with a Case & While structure, but under most circumstances the code will
operate just like a Sequence so I'd rather not have to manual
ly "step" the
Case index and stuff the whole thing in a While Loop.

Thank you!

There is no way (that I know of) to "break" out of a sequence

You have come up with the only 2 solutions to the problem.
You can use CASE inside each frame and pass a BOOLEAN
to each (or in your case put a case around step 2 and 3)
or
You ca
n use the CASE - WHILE structure that is essentially
a state machine.
