st: Looping through a variable list

I would like to loop my estimations through an increasing number of variables, but I am having difficulty undating my varlist.

For example, suppose there were four variable (A B C D) and I wish to estimate x on y where x is one of the four sets: "A", "A B", "A B C", and "A B C D".

tokenize "A B C D" local i = 1 local x = "" while i<=4 { local x = `x'+``i'' regress y `x' local i=`i'+1 }

This program does not work because I can not get x to update. Any ideas?
