Stop in subvi also aborts execution of mainvi

[Greg823]

IS there any function that allows you to stop the mainvi's execution via the subvi i.e. stop the running of the program entirely?

Thanks

Yes, it can be done.  There are various ways to do it (pass a control refereence to the subvi, use a Functional Global, etc.)  Please give us some more details about your specific situation.

There is no generic function for doing that, except the Quit LabVIEW node and it shutsdown LabVIEW completely. That will work, but like a friend of mine once said:

"You can sucessfully stop you car by running it into a tree -- but there can be unintended consequences..."

The problem is that if you quit LV in a subVI there is no orderly shutdown, execution stops immediately. And depending upon what your code is doing this can be a Very Bad Thing.

What exactly is it that you are wanting to accomplish? How is the program in question structured?
