Yep, those're the ones. If I'm not mistaken, the syntax is like this:
Code:
SETV a1, 2 ; Load FFC #2 into a1
LOAD1 d0, y ; Load FFC #2's Y position into the current FFC's d0
SETA1 x, d1 ; Set FFC #2's X position to the current FFC's d0
Basically, for LOAD1 and LOAD2, the first argument is in the current FFC and the second argument is in the other FFC, and SETA1 and SETA2 are the other way around. They all set the first argument's value to that of the second argument.
I believe that will work, but it's not what the compiler does. It uses an argument called REFFFC. I'm not sure how that works.
