I have one column that demonstrate each people's birthd.

Column contains 2million people's information(each are different and format yymmdd8. / ex : 19910111)

I want to dadd 65days to each people's birthd.

Much help appreciated. Thanks. Jamie.

To do this, you will need to study a little on how SAS handles dates.  If BIRTHDT were actually a SAS date, you could just use:

 

newvar = birthdt + 65;

format newvar yymmdd10.;

 

However, I suspect that BIRTHDT is really just a number and 19110111 is really just 19,110,111.  In that case, it needs to be converted to a SAS date first:

 

birthdt = input(put(birthdt,8.), yymmdd8.);

format birthdt yymmdd10.;

 

Then you can use newvar = birthdt + 65;
