bufnum: system variable
Default value: none
This variable contains the number of the current buffer. Setting it
in an EEL program switches to a different buffer. If the indicated
buffer does not exist, nothing happens. Use this method of switching
buffers only to temporarily switch to a new buffer; use the
to_buffer( ) or to_buffer_num( ) subroutines to change
the buffer a window will display.
