What you should put at the end of your loop is:
something like this.
 
 CREATE one FROM two;
   APPEND FROM three;
 
one is the name of a sas dataset (you may need to have it renamed in your
loop).
 
two is the name of matrix defined previously in your IML session (two =
J(1,n,0))
it gives to ONE the dimensions of two.
 
and APPEND FROM three fills the data ONE with the content of matrix THREE.
(you may need to have it renamed in your loop).
 
You can use the same name in the 3 fields.
 
Hope this help
