/CHARACTER_SET

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

 Determines the character set you want TPU to use to display 8-bit
 characters.  The choice of character set affects how TPU 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 TPU to look the same when
 printed, you must choose the same character set for both TPU 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 TPU 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 TPU 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, TPU uses the DEC_MCS character set.  For
    example, the following command invokes TPU, 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.
