Logical_Names

 You can define the following logical names for TPU and EVE startup
 files and other features instead of having to use command-line
 qualifiers:

 Logical names          Definitions and usage
 ---------------------------------------------------------------------
 EVE$INIT               EVE initialization file, typically to set
                        margins, tab stops, and other attributes, or
                        to define keys.  See help on /INITIALIZATION.

 EVE$KEYPAD             EVE keypad.  This logical lets you choose
                        between the various keypads.  Valid
                        equivalence names are EDT, EVE, NUMERIC,
                        VT100, and WPS.  If the logical name is not
                        defined, the keypad defaults to EVE which
                        gives the VT100 keypad on VT100 terminals or
                        the NUMERIC keypad on VT200 and later
                        terminals.  This logical name overrides any
                        keypad setting saved in a section file.  Users
                        can override the effect of this logical name
                        by setting the keypad in their initialization
                        file or command file.  This logical name has
                        no equivalent qualifier.

                        If you extend EVE with your own keypad, you
                        can also define the logical name to be the
                        name of your keypad.  For example, assume you
                        have created a keypad named SIMPLE, and have a
                        procedure named EVE_SET_KEYPAD_SIMPLE that
                        sets the keypad.  If you define the logical
                        name to be SIMPLE, EVE will invoke your keypad
                        during startup.

 TPU$CHARACTER_SET      Character set to use to display characters
                        having the 8th bit set.  This affects how
                        TPU converts text to lowercase or
                        uppercase, and how it removes diacritical
                        marks from text.  See help on /CHARACTER_SET.

 TPU$COMMAND            TPU command file to extend EVE, set up a
                        special text-processing environment for batch
                        editing, or create your own application.  See
                        help on /COMMAND.

 TPU$DEBUG              TPU debug file to be compiled and executed
                        when you use /DEBUG.  Defining TPU$DEBUG does
                        not automatically run the debug file when you
                        invoke TPU.

 TPU$DISPLAY_MANAGER    Screen display or interface.  See help on
                        /DISPLAY or /INTERFACE.

 TPU$JOURNAL            Directory for buffer-change journal files.
                        Does not apply to keystroke journal files.
                        Default is SYS$SCRATCH.  See help on /JOURNAL.

 TPU$SECTION            Section file---either a customized version of
                        EVE or an application you created.  Default is
                        EVE$SECTION.TPU$SECTION, the standard EVE
                        section file.  See help on /SECTION.

 TPU$WORK               Work file which TPU uses to swap memory for
                        editing very large files.  See help on /WORK.

 Defining TPU$COMMAND or EVE$INIT makes startup faster than having the
 editor search for the respective default file.  For example, if there
 is an EVE initialization file you want to use for all or most editing
 sessions, you should define EVE$INIT to specify that file, rather
 than have EVE search for the EVE$INIT.EVE file.  You can put the
 definitions in your LOGIN.COM file.

 To override a definition, use the relevant command-line qualifier.
 For example, if you defined TPU$COMMAND but want to use a different
 command file for a particular editing session, use /COMMAND= and
 specify the command file; or if you do not want a command file used
 for a particular editing session, use /NOCOMMAND.
