heh, you should study docs a little bit imo ;-) 'some is part of parse dialect ... 'some - repeat untill "some digit" is matched 'any - repeat untill "no or more" digits are matched thru - move "thru" matched string to - move "to" matched string 'copy str to "something" - copy everything from current position to something , put result in 'str etc. Cheers, -pekr-
