I have a data set.
Variable1 Variable2 Variable3 Variable4
3 5 6 4
5 7 8 2
I want SAS to read Variable4 and make that many copies of the data. So the above would be converted to:
Variable1 Variable2 Variable3
3 5 6
3 5 6
3 5 6
3 5 6
5 7 8
5 7 8

data want;
set have;
do i = 1 to variable4;
output;
end;
drop i variable4;
run;
Should get you started.
For some purposes you could use variable4 as a FREQ variable, indicating the number of identical records, without creating a new data set. For some others, such as PROC Freq can use variable4 as a WEIGHT variable for the same purpose.
