Here's a routine lifted from euphoria\bin\search.ex

function blank_delim(sequence s)
-- break up a blank-delimited, \n-terminated string,
-- to return a sequence of words
    sequence list, segment
    integer i

    list = {}
    i = 1
    while i < length(s) do
        while find(s[i], " \t") do
            i = i + 1
        end while
        if s[i] = '\n' then
            exit
        end if
        segment = ""
        while not find(s[i], " \t\n") do
            segment = segment & s[i]
            i = i + 1
        end while
        list = append(list, segment)
    end while
    return list
end function
