-- Offset in place:
function Parse1 pStr, pSrc
   put 0 into tStart
   repeat
     put offset(pStr, pSrc, tStart) into tOS
     if tOS = 0 then exit repeat
     add tOS to tStart
     put tStart &cr after tOut
   end repeat
   return tOut
end Parse1


-- Delete as you go:
function Parse2 pStr, pSrc
   put 0 into tStart
   repeat
     put offset( pStr, pSrc) into tOS
     if tOS = 0 then exit repeat
     delete char 1 to tOS of pSrc
     add tOS to tStart
     put tStart &cr after tOut
   end repeat
   return tOut
end Parse2
