Hello there,

I have a dataset where one variable have some missing
value.
I want to replace the missing value with the value
above
it under the same LNUM. The original data is


    ID      LNUM     clm

    483    9048     J085
    483    9943
    483    2652     H915
    483    2652


I need to create a new variable that takes the same
value for
CLM under the same LNUM, so the new variable looks
like:


    ID      LNUM     clm      clm2

    483    9048     J085      J085
    483    9943
    483    2652     H915      H915
    483    2652               H915


I tried to use RETAIN, but it assigns the value for
LNUM 9943,
which is not supposed to:

    ID      LNUM     clm      clm2

    483    9048     J085      J085
    483    9943               JO85
    483    2652     H915      H915
    483    2652               H915


My code is


data d2;
   set d1;
   by id lnum;
   retain clm2;
   if clm  ne ' ' then do;
      clm2=clm;
      end;
run;



Any help would be appreciated.
