It's easy enough to fix Johanne's code to bypass the the size
difference problem:
-Steve
*************
clear*
sysuse auto, clear
drop gear_ratio displacement
save newauto, replace
sysuse auto, clear
qui ds
loc first `r(varlist)'
des using newauto, varlist
loc second `r(varlist)'
loc diff12 : list first - second
loc diff21 : list second - first
di in red "In 1st, not 2nd: `diff12'"
di in blue "In 2nd, not 1st: `diff21'"
*************
