Hi,
You can use proc transpose:

Proc transpose data=have out=want (drop=_:) prefix=CD;
Var CD;
By ID;
Run;

This is called a transpose and you can use PROC TRANSPOSE. 

If you want just a report, PROC FREQ or TABULATE will do it.

Hi,

My data like this:

ID  CD  time treatment

1     3       1        2

1     4       2        2

1     5       3        2

2     6       1        4

2     7       2        4

2     8       3        4

How do I change data like this:

ID       CD1          CD2           CD3        

1           3                4               5

2           6                7               8

From your link, I wrote my code:

proc transpose data=AIDS  out= Output (drop = _NAME_) prefix=CD_;
id time;
var CD;
by ID;
run;

If I add another variable treatment in the data, like this

ID       CD1          CD2           CD3        treatment

1           3                4               5                2

2           6                7               8                4

What should I do? I appreciate your help.

Add the variable to the BY statement or a COPY statement.
