I don't have SPSS on this machine, so the following is untested, but I think it might work. You may need an EXECUTE after the loop.

numeric i1 to i4 (f1.0). /* 4 indicator variables. recode i1 to i4 (else=0). /* initialize to 0. vector v = v1 to v4 / i = i1 to i4. loop # = 1 to 4. - compute i(v(#)) = 1. /* value stored in v(#) flagged as present. end loop. compute unique_values = sum(i1 to i4).
