How can we generate continous numbers for var seq=1,2,3...unitl end of
observations
I need to use retain.
Thanks
john

to assure that you have one as start and Number-of-rows as your high-value
use this program.

Note: Nrows is an _automatic_ variable and is not saved.

DATA Work.NumberedRows;
do RowNmbr = 1 to Nrows;
   set SAShelp.Class
       nobs = Nrows;
   output;
   end;
stop;
Proc Print data = &SysLast.;

run;


compare to:

DATA Work.NumberedRowsX;
retain RowNmbr 0;
do until(EndoFile);
   set SAShelp.Class
       end = EndoFile;
       RowNmbr+ +1;*increment RowNmbr;
   output;
   end;
stop;
Proc Print data = &SysLast.;
run;
