The minus literal character & (an ampersand) replaces a negative
    sign in a field's value with a literal you supply. If the field's
    value is positive, this character moves a blank to the string
    instead of the literal you supply.
    Do not use this character within an edit string that contains
    another character designating a sign.

    Translation of CDO Minus Literal Edit Strings shows how CDO
    translates CDO minus literal edit strings for other languages.
    If CDO characters other than CR or DB appear in a string,
    CDO translates the string as a hyphen (-) for COBOL, DIGITAL
    DATATRIEVE, and PL/I. CDO passes any CDO character to RPG without
    performing a translation.
