-- This single procedure is here to get around Rovner's refusal to put an "empty" TV into the RTTypes world.  The empty TV is 
returned from procedures that have no return values.  This makes it easier to live in the RTTypes world.

DIRECTORY
  RTBasic USING [TV];

BBEmptyReturn: CEDAR DEFINITIONS = BEGIN

  TheEmptyReturn: PROC RETURNS [RTBasic.TV];
  -- returns the special empty TV

  END.
