st: Overriding dropping of collinear variables

[James Valcour <jvalcour@rogers.com>]

Is there a way to tell Stata (either v7 or v8) not to drop collinear variables? 
 Usually I wouldn't try and do this, but I'm trying to compare some output 
produced from SAS's proc genmod with some glm output from Stata. SAS doesn't 
automatically drop collinear variables.  I'm trying to do this because all the 
examples from a course I recently took were in SAS and I'm trying to see if I 
can get the same results from Stata.

I'm a regular Stata user and after using SAS again (I hadn't used it in a number 
of years) I'm even more of a proponent of Stata.

Thanks!
