Ahh, yes...so basically you enable or disable each particular relay 
closure individually with the GPI Enable command (for some reason I 
initially missed that command in the guide). So in my example we would 
do something similar to:
GE 1 I 1 1!
GE 1 I 2 1!
GE 1 I 3 1!

Probably make a macro that disables them all first then set the specific 
ones we need for any particular program. OK, so now I see how it works 
and how it relates to our current system. Good deal! Thanks for that 
nudge in the right direction.
