I propose that the following should work in order to make generic

possible; the matrix should be simply empty ({}).
list myl = null
matrix checkmat = { myl }
OK, done in CVS. Also done:
list L1 = ...
list L2 = ...
list L3 = L1 || L2 # union
list L3 = L1 && L2 # intersection
matrix m = {1,2,3,4}
list L = m # OK provided there are at least 4 variables
# in the dataset
Allin.
