PROC PLAN does not really do random sampling. It can be used that way
but it is not as easy as a data step. Or better still SURVEYSELECT.
Plus way back when PROC PLAN did not even have an OUTPUT statement.
It's function has been significantly enhanced recently.
So even my simple example of permuting 100,000 integers and creating a
SAS data set was not directly obtainable with PROC PLAN before the
enhancements.
