VMS Help MACRO, VAX MACRO Assembler, Directives, .CROSS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Controls which symbols are included in the cross-reference listing.

      .CROSS [symbol-list] (Default)
      .NOCROSS [symbol-list]

    symbol-list

    A list of legal symbol names separated by commas.

    When you specify the /CROSS_REFERENCE qualifier in the MACRO
    command, VAX MACRO produces a cross-reference listing.  The
    directives have an effect only if /CROSS_REFERENCE was specified in
    the MACRO command.

    Using .NOCROSS  with  a  symbol  list  disables  the
    cross-reference listing for the listed symbols only.  Using .CROSS
    with a symbol list enables or  reenables  the  cross-reference
    listing  of  the  listed symbols.
