Why don't you make a 2D array of (11,11) corresponding to the sum of
all possible values of A and B?

For each value of (A+B), the value of C is immediately determined as
1-(A+B), or it does not exist if (A+B)>1. Thus, for each entry in the
matrix, you can read off A and B from the column and row labels, and C
from 1-(A+B).

Good luck,
Craig

aa = lindgen(11) # (lonarr(11)+1) ;; A-only matrix
bb = (lonarr(11)+1) # lindgen(11) ;; B-only matrix
cc = 10-(AA+BB)
wh = where(cc GE 0)
a = wh MOD 11 & b = wh/11 & c = cc(wh)
