COMMENT \
THIS ROUTINE DEFINES THE EQUIVALENCES BETWEEN THE ASCII,
SIXBIT AND EBCDIC CHARACTER SETS. IT DOES THIS BY DEFINING A SET
OF SYMBOLS FOR EACH CHARACTER SET. THE FORM OF A SYMBOL IS:
<LETTER 1><LETTER 2>%<NUMBER>
WHERE:
LETTER 1 INDICATES THE CHARACTER SET TO WHICH THIS
SYMBOL BELONGS.
LETTER 2 INDICATES THE CHARACTER SET TO WHICH THE
VALUE OF THIS SYMBOL BELONGS.
NUMBER INDICATES THE PARTICULAR CHARACTER TO WHICH
THIS SYMBOL BELONGS.
THE VALUE OF THE SYMBOL IS THE CHARACTER, IN THE CHARACTER SET
INDICATED BY <LETTER 2>, TO WHICH THE CHARACTER REPRESENTED BY THE
SYMBOL IS EQUIVALENT.
THE CHARACTER SETS AND THE LETTERS USED TO REPRESENT THEM ARE:
SIXBIT S
ASCII A
EBCDIC E
UPPER U
EXAMPLES:
SYMBOL VALUE EXPLANATION
SA%20 60 SIXBIT 20 ("0") IS EQUIVALENT TO ASCII 60 ("0").
SE%20 360 SIXBIT 20 ("0") IS EQUIVALENT TO EBCDIC 360 ("0").
AS%60 20 ASCII 60 ("0") IS EQUIVALENT TO SIXBIT 20 ("0").
ES%360 20 EBCDIC 360 ("0") IS EQUIVALENT TO SIXBIT 20 ("0").
AU%141 101 ASCII 141 ("a") IS EQUIVALENT TO ASCII 101 ("A")
IF A SYMBOL IS ASSIGNED A DEFAULT VALUE BECAUSE IT HAS NO
EQUIVALENT IN THE CHARACTER SET, THE VALUE WILL HAVE BIT 18 SET TO 1.
