In my experience, computing summary statistics on a huge number of variables is of very limited usefulness, and not worth the time to do it. So I don't do this any more.
Nevertheless, if you are going to do this, I think it would make more sense to save the output in a SAS data set, in which you could actually search, and later analyze, rather than a huge number of HTML outputs as in the method from @ed_sas_member .
