    Not sure why this happens  (maybe acn can elucidate) -- Reduce was
    originally developed for interactive use and  consequently tries to
    break long lines at meaningful points  -- not always successfully.

    It is better to start  Reduce (with redcsl or redpsl according to taste)
    and then do #000000

    in "file.red"$

    Output from the individual commands in the file can be controlled by
    using semicolon or dollar as desired.
