Tony <Peter.Lachenbruch@oregonstate.edu> :
There are many ways to go, and the optimal choice no doubt depends on
what you might want to do with the data later, but try e.g.

clear
input str15 other
"55.1"
"0"
"54.3"
"0"
"0"
"55.2"
"0"
"0"
"17.3;49.3"
end
g o=other if other!="0"
replace o=subinstr(o,";"," ",.)
g n=wordcount(o)
l, noo
