Whoops, the old code remnant strikes again! My parse() function was
unnecessarily using a separate variable for the list sequence length. Here's
the "corrected" function:

 ------------------------------------------------------------------------

function parse(sequence s, object x)
 -- parse s based on delimiter x into a sequence of values
 -- NOTE: we append x to s so we have at least one delimiter, at the end
sequence list
integer prev, curr

   list = find_all(x, append(s, x)) -- list of delimiter positions
   prev = 0
   for i = 1 to length(list) do
      curr = list[i]
      list[i] = s[prev+1..curr-1]
      prev = curr
   end for

   return list -- now, a list of the delimited values
end function

 ------------------------------------------------------------------------

The rest of the functions should be just fine. Please note that find_last(),
find_all() and parse() are general-purpose routines which can be used for
many other purposes.


Be seeing you,
