JRO UP? As in pulling in a value from the up port. I didn't see how that gives me a whole lot since wouldn't I need to know in the other node what the offset would be? I considered that this would be valid, but I couldn't see a way to make it really useful.
It allows you to use another processor to do control flow based on an input, freeing up cpu time. For example, suppose you wanted to emit to DOWN:
0 if LEFT is <= 0
UP if LEFT is > 0
So you have two options
S: MOV LEFT ACC
JGE E
MOV 0 DOWN
MOV UP NIL
JMP S
E: MOV UP DOWN
Or you could do this:
S: JRO LEFT
MOV UP NIL
MOV 0 DOWN
JMP S
MOV UP DOWN
And left would send 1 if its value is <= 0, or 4 if it's >0. In this case it only saves one cycle for the node under consideration, but it could be a good deal more if the conditional is more involved.
