This macro uses PROC DATASETS to delete the data set that is passed to the macro. CALL EXECUTE is used to run PROC DATASETS once the DATA Step has executed.

The macro works with a permanently stored data set or a temporary data set.

This technique is needed only if you want to invoke a macro from within the DATA Step to delete the data set once processing has completed.
