Your variable list is in global macro S_E_vl 
after -logistic-. Your response is in S_E_depv. 
So here is one way to do it; there may be 
better ones. Looking in e(b) is about as 
much work as this. 

After such a model, if you type 

. covars 

you will see a list and in addition 
the list will be in local macro -covars-. 

Here is -covars-

program covars 
	version 8.2
	capture local covars : subinstr global S_E_vl "$S_E_depv" "" 
	if _rc { 
		di as err "no covariates known?"
		exit 498
	} 	
	di as txt "`covars'" 
	c_local covars `covars' 
end
