How to rename all the variables as X1-X10?

[sunrain]

Hi, everyone:

Finally I found that call sortn can be used to sort data observation wise.
But the restriction is that the names in the array should be uniform as X1-X10. Otherwise the command does not work with out warning.

Can anybody teach me to rename all the variables such as X1-X10?

I don't think call sortn really cares. Here are two examples, one with and one without renaming:
[pre]
data want1;
set sashelp.class;
array nums(3) age--weight;
if name eq "Judy" then weight=50;
call sortn(of nums(*));
run;

data want2;
set sashelp.class (rename=(age=x1 height=x2 weight=x3));
array nums(3) x1-x3;
if name eq "Judy" then x3=50;
call sortn(of nums(*));
run;
[/pre]
HTH,
