Thanks so much. It's still not working correctly, but I'm trying not to ask a whole bunch of noob questions. I've been working in Labview for the last 15 years and haven't touched text based programming much since the 6502 in assembly.
The important thing I've gleaned from this is that the array form cant be used for reads which is all I want to do. I don't need to send data.
It's more important to me that I understand how this all works rather than just finding some code that works.
