Subject: Re: Question about PROC FREQ
Major differences between your different PROC FREQs are:
1) the edu*age*sex one needs a sort by CLUSTER only,
the other one requires a sort on CLUSTER, AGE and SEX.
2) the edu*age*sex one may fail when the number of possible
combinations exceeds some 32756
3) the edu*age*sex one definitely wins on performance when
the number of possible combinations remains below those
