A "char" configured as signed in EBCDIC violates the ANSI C standard,
which says:
If a member of the basic execution character set is stored in a
char object, its value is guaranteed to be positive.
whereas the "basic execution character set" is defined as:
Both the basic source and basic execution character sets shall have
the following members: the 26 uppercase letters of the Latin
alphabet
A B C D E F G H I J K L M
N O P Q R S T U V W X Y Z
the 26 lowercase letters of the Latin alphabet
a b c d e f g h i j k l m
n o p q r s t u v w x y z
the 10 decimal digits
0 1 2 3 4 5 6 7 8 9
the following 29 graphic characters
! " # % & ' ( ) * + , - . / :
; < = > ? [ \ ] ^ _ { | } ~
the space character, and control characters representing horizontal
tab, vertical tab, and form feed.
Do people actually used signed "char" with EBCDIC?
