Ok, so the previous thread i started, i don't think can be accomplished as stated. But i think this will work:
I'm trying to do a many-to-many match merge, but i have a problem: rather than having 1 variable = 1 variable, i have 5 variables to merge "by". I don't think i can do this in SAS, but it would also work to have the 5 variables compound to one variable showing each of the permutations of the 5, then doing the merge by the new single variable. I could then do the merge using Proc SQL with: one variable showing the permutations = one variable showing the permutations.
