If you wanted to embed similar code in a do file or program to be used
frequently, you could for efficiency rewrite using -summarize,
meanonly-.

Martin complains that -total- (like -mean-, presumably) performs
listwise deletion (unlike, say, -summarize-). To get around this:
--------------
clear all
sysuse auto
local mw price mpg rep78
foreach v of local mw {
qui total `v'
mat b = nullmat(b),e(b)
mat en = nullmat(en), e(_N)
}
mat list b
mat list en
