Hello. Maybe someone can shed light on this most likely simple issue. I'm a newbie to this. Attached is a test program and I am toying with writing to data files from inputs for a practical application on a different machine.

Ladder 8, Rung 2, what am I doing wrong that info is not moving into data file? Any info is appreciated.
 
I guess first questions:

Is I:2/1 in ladder 2 coming on so that the program executes subroutine #8?
Is I:2/2 coming on to execute the CMP instruction?
 
dginbuffalo, thanks! Silly me. Put it above the subroutines and got it working. Appreciate the quick follow-up.
