Content-Type: text/plain; charset=us-ascii

8.2 on WIN XP

Hi all,

I have a file (CODES) with about 20,000 records:
with:  Year, F, S, M and U as variables.

I just want to keep all the U where F, S and M are
unique for that YEAR.

I know i need do loops but I just need a start to do
this.

Any help will be appreciated greatly.


data filecodes;
 input year     4.
          f   $ 2.
          s   $ 2.
          m   $ 5.
          u   $ 7.;
run;
