Proc Logistic Predictor Variables

Guys, I am trrying to do a logistic regression similar to:

proc logistic data="c:\data\binary" descending;
class rank / param=ref ;
model admit = gre gpa rank;
run;

Problem is, I have hundreds of variables in my dataset. Is there a way to not have to type them all out?

On possibility is to use the "--" notation to get a number of variables that are adjacent in the dataset (do a PROC CONTENTS with the POSITION option to see the order). If you have variables

a b c ...x y z

then you can reference all 26 as a--z

- ritam, just to clear things up

the names of the variables actually dont matter. by using the "--" notation you are including everything from the var_1-var_n
