If you write text to an existing file, the new text is added to the end of
the existing text.
If you write text to a printer, the copy contains line numbers if you see
them on your screen. SHOWNUMBER ON gives you line numbers
when you print the file; SHOWNUMBER OFF does not.
After you enter the WRITE command and see the response line, you can
press the HELP key once to see a short help text and twice to see the
complete help text.
