	status.i4.v = blt_get_tag(machine.i4.v, buffer.i4.v, request.s.r)

	This routine accepts an integer indicating the machine to be viewed,
	an integer indicating the buffer to be viewed and a data structure 
	to be filled with Tag data.

	machine		BLT_TEVATRON, BLT_MAIN_INJECTOR, BLT_TEST or
			BLT_RECYCLER as defined in ul_cbsaux:bltuti.h
	buffer		buffer designation between 0 and BLT_MAX_BUFFER in
