/OUTPUT=output-file
       /NOOUTPUT (default)

    Controls how the output file is named at the end of your editing
    session. By default, the output file has the same name as
    the input file but is given the next higher available version
    number. Use the /OUTPUT qualifier to give the output file a file
    specification different from the input file.

    The following command line invokes TECO to edit a file named
    MEMO.DAT and gives the resulting output file the name OUTMEM.DAT:

      $ EDIT/TECO/OUTPUT=OUTMEM.DAT MEMO.DAT

    You can include directory information as part of your output file
    specification to send output to another directory as follows:

      $ EDIT/TECO/OUTPUT=[BARRET.MAIL]MEMO.DAT MEMO.DAT

    No wildcard characters are allowed in the file specification.
