SET(PERMANENT)

 Sets a buffer to permanent, so it cannot be deleted.  This is useful if
 you create buffers for procedures to use in manipulating text or storing
 data.  By default, buffers are not permanent.

 Syntax

    SET (PERMANENT, buffer)

 Example

    SET (PERMANENT, paste_buffer);

 Sets the paste buffer to permanent, so it cannot be deleted.  Once you set
 a buffer to permanent, it cannot be reset so that it can be deleted.
