Kat,
what do you get if you code it this way instead...

 while 1 do
    if not sequence(TheWebPage[junk][1]) then
        puts(1, "Not a sequence\n")
        exit
    end if
    if not match(" ",TheWebPage[junk][1]) then
        exit
    end if
 . . .
 end while

However, I take it that 'TheWebPage[junk]' is supposed to contain a line of
text. If that is so, then I would expect that 'TheWebPage[junk][1]' would
contain an atom - namely the first character in the line.
