In a word, -tokenize-.
program myprog, rclass
syntax varlist(numeric min=3) [if] [in]
marksample touse
qui count if `touse'
if r(N) == 0 error 2000
tokenize "`varlist'"
su `1' if `touse', meanonly
local mean1 = r(mean)
su `2' if `touse', detail
local median2 = r(p50)
su `3' if `touse'
local sd3 = r(sd)
return scalar results = `mean1' + `median2' + `sd3'
end
