  /132      Enables 132 column, 16 color text video (XGA).
 [d:][path][filespec]  Specifies drive, directory, and file to edit.
  =         Is shorthand for "same path as last specified" at the DOS

            For example, E \PAS\LANG\FOO.PAS =FOO.BAK will load the two
            files FOO.PAS and FOO.BAK, both from the directory \PAS\LANG.
