COMMENT \
THIS MODULE DEFINES THE NUMERIC VALUE INTO WHICH A CHARACTER,
IN THE SIXBIT, ASCII OR EBCIDC CHARACTER SET, WILL BE CONVERTED. IT
DOES THIS BY DEFINING A SET OF SYMBOLS FOR EACH CHARACTER SET. THE
FORM OF A SYMBOL IS:
<LETTER>N%<NUMBER>
WHERE:
LETTER INDICATES THE CHARACTER SET TO WHICH THE SYMBOL BELONGS.
NUMBER INDICATES THE SPECIFIC CHARACTER.
THE VALUE OF THE SYMBOL CONTAINS THE FOLLOWING INFORMATION:
BIT 26 1==>THIS CHARACTER IS A LEADING CHAR.
BIT 27 1==>THIS CHARACTER IS A SPECIAL CHAR.
BIT 28 1==>THIS CHARACTER HAS AN OVERPUNCHED "-".
BITS 29-35 THE NUMERIC VALUE OF THE CHARACTER UNLESS
IT IS A SPECIAL CHARACTER IN WHICH CASE
THIS FIELD CONTAINS A NUMBER WHICH TELLS
WHICH SPECIAL CHARACTER IT IS.
THE LEADING CHARACTERS ARE:
<NULL>, <BLANK>, <TAB>.
THE SPECIAL CHARACTERS ARE:
CHARACTER VALUE
<NULL> 0
"+" 1
"-" 2
TERMINATING 3
THE TERMINATING CHARACTERS ARE <TAB> AND, IF THE SWITCH TRAILB
IS SET TO 0, <BLANK>.
FOR SIXBIT AND ASCII:
THE CHARACTERS 0-9 ARE TRANSLITERATED TO THE NUMBERS 0-9.
THE CHARACTERS A-I (UPPER AND LOWER CASE) ARE TRANSLITERATED
TO THE NUMBERS 1-9.
THE CHARACTERS J-R (UPPER AND LOWER CASE) ARE TRANSLITERATED
TO THE NUMBERS 1-9.
THE CHARACTERS <BLANK>, "]", "!", ":", "[", "?", "{" AND "}"
ARE TRANSLITERATED TO 0.
THE CHARACTERS J-R (UPPER AND LOWER CASE), "]", "}", "!" AND
":" HAVE THE OVERPUNCHED "-" FLAG SET TO 1.
ALL OTHER CHARACTERS ARE FIRST CONVERTED TO ASCII IF THEY ARE
SIXBIT AND THEN THEY HAVE 60 SUBTRACTED FROM THE ASCII REPRESENTATION.
FOR EBCDIC:
ALL CHARACTERS ARE CONVERTED BY SIMPLY USING THE LAST FOUR
BITS OF THE CHARACTER MOD ^D10.
THE CODES 260-271 AND 320-331 HAVE THE OVERPUNCHED "-" FLAG
SET TO 1.

SUBTTL SIXBIT TO NUMERIC EQUIVALENCES.
COMMENT \
USE THE ASCII TO NUMERIC EQUIVALENCES AND THE ASCII TO SIXBIT
CHARACTER EQUIVALENCES TO DEFINE THE SIXBIT TO NUMERIC EQUIVALENCES SO
THAT WE KEEP THINGS CONSISTANT.
