VMS Help EDIT, /TPU, /CHARACTER_SET  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /CHARACTER_SET[={DEC_MCS (default) | ISO_LATIN1 | GENERAL}]

  Determines the character set you want DECTPU to use to display 8-bit
  characters.  The choice of character set affects how DECTPU performs
  the following operations on characters:

  o  Converting to lowercase

  o  Converting to uppercase

  o  Inverting case

  o  Removing diacritical marks

  o  Converting to uppercase and removing diacritical marks

  The choice of character set also affects how your text appears when
  printed.  For the text displayed in DECTPU to look the same when
  printed, you must choose the same character set for both DECTPU and
  the printer.

  There are two ways to specify the character set you want to use:

  o  Define the TPU$CHARACTER_SET logical name to specify the character
     set.

     This lets you use that character set for all editing sessions---
     including when you invoke DECTPU within MAIL or other utilities.
     You can put the definition in your LOGIN.COM file.  For example,
     the following commands define TPU$CHARACTER_SET as ISO_LATIN1, and
     then invoke DECTPU using that character set:

        $ DEFINE TPU$CHARACTER_SET iso_latin1
        $ EDIT/TPU

  o  Use /CHARACTER_SET= and specify the character set on the command
     line.

     This overrides any definition of the TPU$CHARACTER_SET logical
     name.  By default, DECTPU uses the DEC_MCS character set.  For
     example, the following command invokes DECTPU, using the GENERAL
     character set:

        $ EDIT/TPU /CHARACTER_SET=general

  If the character set you specify either with /CHARACTER_SET or by
  defining TPU$CHARACTER_SET is invalid, the editing session is
  aborted, returning you to the DCL level.
