Use the -sieve()- function in Nick Cox's excellent -egenmore- (SSC):
******************************
clear*
input str8 percent str15 words
"45%" "1234 sjkhdfjh kjdfk"
"45%" "1234 sjkhdfjh kjdfk"
"45%" "1234 sjkhdfjh kjdfk"
"45%" "1234 sjkhdfjh kjdfk"
"45%" "1234 sjkhdfjh kjdfk"
end
egen percentnum = sieve(percent), keep(numeric)
egen wordsnum = sieve(words), keep(numeric)
destring percentnum wordsnum, replace
li, clean
su
******************************

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
