Sort numeric sequentially

[mandyosu01]

Hello,

I want to sort years in column sequentially. For example, 

Data have 

id	year
1	1998
1	1998
1	1999
1	1999
1	2000
1	2000
1	2000
1	2000
1	2001

Data want

id	year
1	1998
1	1999
1	2000
1	2001
1	1998
1	1999
1	2000
1	2000
1	2000

Thank you so much!

You'll need to add a variable to indicate the proper order.  For example:

data want;
   set have;
   by id year;
   if first.year then order=1;
   else order + 1;
run;

Then all you need to do is sort the data:

proc sort data=want;
   by id order year;
run;
