standalone Vi within a Vi.

[vamsi539]

hello All, 

                 I am working with an application that needs to run a sub-vi all by itself and return the value to the main Vi when promted by the user. it is like running a subsequence with a main sequence,but as a new execution(TestStand terms). I looked at the other threads about Spawn a process,but find it diffcult to understand them.

Thanks

Use VI server.  As for returning the variable, there are numerous techniques.  My assumption is while this other process is spawned, your original VI will continue to do whatever it is doing, and is not sitting around waiting on a response from the child process.
Some more details may reveal a straight forward path for this.
