I am not sure that this solves my problem

i would like to write a code to enumerate 1-10 in each ID ( i only have a column with ID:s)

data want;

ser have;

by id;

if first.id then count 1 to 10

run;

It's easier if you post two data sets, one that you have and one that you want.

data want;

set have;

do number=1 to 10;

     output;

end;

run;
