I made a mistake on my last post on this subject.

global function trim(object line)-- In case a decimal is sent the error will not
show up in the
-- .e  where trim() is kept (which is not
                                 causing the problem
                                 -- anyway)
    if sequence(line) and length(line)>0 then -- eniminates sending in nothing
-- in any case whatever is sent in
                                             is returned*,
        while find(line[1], " \t\n") do
        line = line[2..length(line)]   -- delete any leading whitespace
            if length(line) = 0 then --if there is nothing but spaces get out
             exit
            end if
        end while
    end if
     if sequence(line) and length(line)>0 then
       while find(line[length(line)], " \t\n") do
         line = line[1..length(line)-1]        -- delete trailing whitespace
       end while
     end if
    return line -- *here
end function
