While this dataset may be sorted and several suggestions for increasing
available MVS resources have been posted, I'd like to suggest you
revisit your algorithm if possible. Often subsetting records,
summarizing (with the NOTSORTED option) along the existing sort order,
and dropping variables can reduce the size of a dataset considerably to
the point that a sort is no longer a major undertaking.
