You probably meant
*************
des using newauto, varlist
*************
right in the middle of your code. My knee-jerk proposal depends on the first
dataset being larger than the second one, BTW...

Betreff: Re: st: AW: compare files, vars only
what about:
*************
clear*
sysuse auto, clear
drop gear_ratio displacement
save newauto, replace
sysuse auto, clear
qui ds
loc first `r(varlist)'
des using auto, varlist
loc second `r(varlist)'
loc diff: list first - second
di in red "Differences: `diff'"
*************
-describe- does not need to load the dataset which may be of interest here
