You might want to read the Euphoria Reference Manual over again:

Because either a sequence or an atom (-1) might be returned by gets(), you
should probably assign the result to a variable declared as object.

That being said, you might try something like:

include get.e

object desc

desc=gets(0)
? desc

if sequence( desc ) then           -- user did not hit Ctrl-Z
  desc = desc[1..length(desc)-1]   -- remove last element from sequence
end if
? desc

-- I'm not sure what you are trying to do below since 'desc' is a sequence
--   unless we've hit 'end of file' or Ctrl-Z

--while desc>0 do
--    puts(1,"!")
--end while

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

Perhaps if you provide more details of what you'd really like to do, then
we could suggest some other, possibly better solutions.
