! THIS FILE CONTAINS THE BINDS OF LEXEME NAMES AND NUMBERS, AND
! THE PRECDENCE OF THE STACKABLE OPERATORS.  ROUTINE EXPRESS
! CONTAINS A PLIT PRECDENCE, WHICH IS SET TO PRCDNCE0, PRCDNCE1,
! ETC.  THIS PROVIDES INDEPENDENCE FOR EXPRESS WITH RESPECT
! TO THE LEXEME NUMBERS AND THEIR ORDERING.  THE ONLY REQUIREMENT
! IS THAT THE PLIT IN EXPRESS CONTAIN THE SAME NUMBER OF ENTRIES AS
! THERE ARE LEXEMES.
!
! FILE LEXAID.BLI CONTAINS THE BINDS FOR THE CHARACTER CASSIFICATION
! CODES AND THEIR NAMES, USED BY ROUTINE LEXICAL.  NOTE THAT THE
! CODE NAMES AND LEXEME NAMES HAVE BEEN OVERLAYED AS MUCH AS
! POSSIBLE SO AS TO MAINTAIN A MINIMUM OF CONFUSION.
!
!------------------------------------------------------------------------------------------------------------------
!LEXEME NUMBERS REPRESENTING SINGLE OPERATORS ARE PREFIXED WITH A 1 IN
!THE 12 BIT FIELD: 1^6+LEXEME NUMBER.
!
!LEXEMES WHICH ARE OPERATORS BUT NOT USED AS AN OPERATOR HAVE NO PREFIX.
!THIS ENABLES THE DIFERENTIATION OF STACKABLE OPERATORS FROM CHARACTERS
!REQUIRED ONLY BY THE SYNTAX.
