If you use the edit string character S (uppercase letter S) only
    once within an edit string, one of the following results can
    occur:

    o  If the field's value is positive, the character S inserts a
       plus sign (+) into the edited value.

       CDO Edit       S9
       String:
       DTR Edit       +9
       String:
       Field Value:   6
       Edited         +6
       Value:

    o  If the field's value is negative, the floating sign character
       inserts a minus sign (-) into the edited value.

       CDO Edit       S9
       String:
       DTR Edit       +9
       String:
       Field Value:   -8
       Edited         -8
       Value:

    o  If the field's value is zero, the effect of the floating sign
       character depends on the language reading the field.

       CDO Edit       S9
       String:
       DTR Edit       +9
       String:
       Field Value:   0
       Edited         +0
       Value:

       If you use more than one floating sign character at the
       beginning of an edit string, the S character suppresses
       leading zeros before inserting a plus sign (+) or minus sign
       (-) into the edited value.

       CDO Edit       SS99
       String:
       DTR Edit       ++99
       String:
       Field Value:   0054
       Edited         +54
       Value:

    You cannot use the S character within an edit string that
    contains another character designating a sign.
