EVE SET_BUFFER — VMS 5.1-B

 SET BUFFER

 Sets the editing status of the current buffer, shown in the status line.
 This determines whether you can modify the buffer or whether EVE saves
 (writes out) the buffer on exiting.

 You can specify one of the following keywords (per command):

    Keyword         Effects
    ---------------------------------------------------------------------
    READ_ONLY       Buffer is write-locked and unmodifiable.  Text editing
                    functions do not work in the buffer and on exiting, EVE
                    does not write out (save the buffer).

    WRITE           (Default setting.)  Buffer is write-enabled.  On
                    exiting, if the buffer has been modified, EVE writes it
                    out or asks if you want to write it out.

    MODIFIABLE      (Default setting.)  Buffer can be modified.  Also
                    restores the previous mode of the buffer (insert or
                    overstrike).

    UNMODIFIABLE    Buffer cannot be modified.  In the status line,
                    Unmodifiable replaces Insert or Overstrike.

 o  Typically you set a buffer to READ_ONLY, UNMODIFIABLE, or both to
    prevent inadvertently changing text you want to keep intact, such as
    reference data or a previous draft.

 o  If you create a "scratchpad" buffer as a temporary storage area, you
    may want to set it to READ_ONLY and MODIFIABLE; this lets you edit the
    buffer, but EVE does not write out that buffer on exiting.
