"where" calculates where setpos will be:

to where :l
make "ps projectsize
make "w (first :ps) / 2
make "h (last :ps) / 2
make "x :w + first :l
make "y :h + last :l
output list (remainder :x :w * 2) - :w (remainder :y :h * 2) - :h
end


t1, setpos [1000 1000]
t2, setpos where [1000 1000]

show where [1000 1000]
256 148
