st: non-mutually exclusive factors

["Benhoen2" <benhoen2@earthlink.net>]

I have some factors that are not mutually exclusive and i want to bin my
data among the various permutations of the factors. 

For example say there are two factors A and B.  There are 4 possibilities:
none, A, B and AB.  For 3 factors A B & C there are 8 possible outcomes:
none, A, B, C, AB, AC, BC, and ABC.  As the number of factors grows the
number of permutations doubles, e.g., 5 factors have 64 permutations.  

Is there any clever .do file to bin cases between multiple factors?  Or
alternatively any advice on a loop file that both bins the cases, and uses
the factor name to create labels.  I have 5 factors I am interested in
binning between.

Thanks, as always,

Ben
