Testing all combinations of a model statement (proc logistic)

I seem to remember that there is a way to test all possible combinations of a model all in one statement.

so lets say

proc logistic data=x;

model y= a b c d e f;

run;

it would give you the results for:

etc....

Am I imagining things?

You can build a model with all interaction terms by using the "bar notation" such as

model y = a | b | c | d;

or restrict to only second order interactions with

model y = a | b | c | d @2;

As Data Null says, you can use variable selection to select a model that incorporates a subset of the terms listed on the model statement.
