Here's a model:

================================MOD ENDS============================

Only the items between the MOD BEGINS and MOD ENDS should go in the .mod file.
I don't have your program, so don't have a clue how to implement it. Good luck.

 

Try this Google:

I found a thread using that search that National Instruments was the source for that model:
http://www.edaboard.com/ftopic288072.html

There are lots of other links to follow from that search.

 

Thanks Sgt. I got the part.
