-summarize- calculates the sum, but does not present it.
This is documented at [R] summarize p.153.
Here is a quick hack.
program mysum
version 8
syntax varlist(numeric) [if] [in]
marksample touse
qui count if `touse'
if r(N) == 0 error 2000
di
foreach v of local varlist {
su `v' if `touse', meanonly
di as txt "`v'{col 33}" as res %12.0g r(sum)
}
end
e.g. mysum <varlist>
