  32 --  SPITBOL tables with boolean values (sets)
  33
  34 --  This package provides a predefined instantiation of the table abstraction
  35 --  for type Standard.Boolean. The null value is False, so the only non-null
  36 --  value is True, i.e. this table acts essentially as a set representation.
  37 --  This package is based on Macro-SPITBOL created by Robert Dewar.
