/PUNCTUATION_CHARACTERS=string
       /PUNCTUATION_CHARACTERS=",;()" (D)

    Specifies the characters that are considered punctuation marks,
    or delimiters, in the language. When a placeholder name and its
    enclosing brackets are deleted, preceding white space is also
    deleted if there are punctuation characters to delimit the program
    constructs. If you do not specify a value for the /PUNCTUATION_
    CHARACTERS qualifier, then the value is reset to the default
    ",;()". If you omit the /PUNCTUATION_CHARACTERS qualifier, the
    current value remains in effect.
