!	TOKTYP.REQ
!
!
!	This REQUIRE file contains all the definitions 
!	relating to the global block "token".
!
!
! REVISION HISTORY
!
!	12-Oct-81	TT	Added s_empty to list of valid token types.
!				This makes us look more like the 10/20.
!				This will be used in the future for parsing
!				empty lexical functions.
!
!	18-Jan-82	TT	Added %require as s_p_require. Note that
!				Bliss syntax says that %REQUIRE is not a
!				declaration.
!
! END OF REVISION HISTORY
