The encoded sign edit string characters are the encoded minus
    edit string character (C), the encoded sign edit string character
    (G), and the encoded plus edit string character (K).

1  –  C Encoded Minus Character

    If the field's value is negative, the encoded minus character C
    (uppercase letter C) overwrites the next digit with a minus sign
    (-), then moves the encoded digit to the edit string.

    If the field's value is positive or zero, this character moves
    the next digit into the edited string.

    Use this character only at the beginning or end of a string.

    An edit string can contain only one character designating a sign.

    Do not use this character within an edit string that contains
    other characters designating a sign.

    See the reference manual for the language or product that will
    interpret the edit string to determine how the language or
    product interprets encoded sign characters.

2  –  G Encoded Sign Character

    If the field's value is positive, the encoded sign character G
    (uppercase letter G) overwrites the next digit with a plus sign
    (+), then moves the encoded digit to the edit string.

    If the field's value is negative, the encoded sign character (G)
    overwrites the next digit with a minus sign (-), then moves the
    encoded digit to the edit string.

    If the field's value is zero, the action of this character
    depends on the language.

    Use this character only at the beginning or end of a string.

    An edit string can contain only one character designating a sign.

    Do not use this character within an edit string that contains
    other characters designating a sign.

    See the reference manual for the language or product that will
    interpret the edit string to determine how the language or
    product interprets encoded sign characters.

3  –  K Encoded Plus Character

    If the field's value is positive, the encoded plus character K
    (uppercase letter K) overwrites the next digit with a plus sign
    (+), then moves the encoded plus digit to the edit string.

    If the field's value is negative or zero, the encoded plus
    character (K) moves the next digit into the edited string.

    Use this character only at the beginning or end of a string.

    An edit string can contain only one character designating a sign.

    Do not use this character within an edit string that contains
    other characters designating a sign.

    See the reference manual for the language or product that will
    interpret the edit string to determine how the language or
    product interprets encoded plus characters.
