Linear Regression Model

[iressa13]

Hello, I am very new to SAS and was wondering how to control for a variable in a linear regression model. 

Here is the the original code to get the initial model. I am trying to control for X1. Thanks for any help!!

proc reg data = WORK.IMPORT PLOTS= NONE; 
model Y=x2 x1;
run;
quit;

Don't you control for a variable by including it in your model, which you've already done? 

Your base model shouldn't include the variables you're trying to control for...

PS. My stats are rusty so I'm moving this to the Stats Forum, so you can get an answer from someone more appropriate.

I dont understand the question. In my terminology, you already control for it?
