DESCRIPTION


	tbldosa 3.1 12/10/90

 Modified:
	8/16/90	chinds	The table was constructed to use only one level
			of indirection in __x_do_func for monoadic
			functions.  Dyadic functions require two
			levels, and the tables are still contained
			in __x_do_func.  The table is arranged for
			index with a 10-bit index, with the first
			7 bits the opcode, and the remaining 3
			the stag.  For dyadic functions, all
			valid addresses are to the generic entry
			point.
