Hi,
Suppost I have data like this:
Date            Var1
07/24/2002      10
07/24/2002      10
...
07/25/2002      12
07/25/2002      12
...
07/25/2002      14
07/25/2002      14
...
How do i get a data set like this:
Date    Var1
07/24/05  10
07/25/05  12
07/26/05  14
Thanks!
Well, I guess I would start by adding 3 to each year (do you maybe mean /02 
instead of /05)?  You can also use -duplicates drop- to get rid of the 
duplicated cases, if that is indeed what you want to do (I'm not sure; you 
might have typos in the data you typed in, or maybe I misunderstand what 
you want).  See -help dfmt- for info on formatting dates.
