     For an overview of the GET_INFO built-in, see the HELP topic GET_INFO.

     TPU orders buffers according to the order in which they are created;
     the first ones created are the first in the list.

     The following strings can be used for parameter2 when parameter1 is the
     keyword BUFFER or BUFFERS:

       Parameter 2       | Return Value (Parameter 1 is keyword BUFFERS)
      -------------------+------------------------------------------------+
       "current"         | Buffer   - Current buffer
                         | 0        - if none
       "find_buffer"     | Buffer   - The buffer variable whose name
                         |            you supply as parameter3.  Note
                         |            that you must supply a third
                         |            string parameter naming the buffer
                         |            to be returned if the second
                         |            parameter is "find_buffer".
                         | 0        - if buffer not found
       "first"           | Buffer   - First  buffer  in  TPU's  internal
                         |            list of buffers
