How to replace the "missing value ." between 2000/01/02 and 2000/02/15 with the value "5" on 2000/01/01?

 

ID     DATE           Variable

01   2000/01/01         5

01   2000/01/02         .

01   2000/01/03         .

01   2000/01/04         .

01   2000/01/05         .

.................

01   2000/02/15         .

01   2000/02/16         7

 

Assuming that there are many ID like '01' and many case like missing value between 2000/01/02 and 2000/02/15. Is there any efficient way to replace these missing value with the most recently available value like '5' in this case before new value like '7' is available?

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets
