    Generates 64 bits (eight bytes) of binary data.

      .QUAD literal
      .QUAD symbol

    literal

    Any constant value.  This value can be preceded by ^O, ^B, ^X, or
    ^D to  specify  the  radix  as  octal,  binary, hexadecimal, or
    decimal, respectively; or it can be preceded by ^A to specify the
    ASCII  text operator.  Decimal is the default radix.

    symbol

    A symbol defined elsewhere in the program.  This symbol results in
    a sign-extended, 32-bit value being stored in a quadword.

    It does not evaluate expressions and that it accepts only one
    value. It does not accept a list.

    .REFn

    Operand generation directives that you can use in  macros  to
    define new opcodes.

      .REF1 byte operand
      .REF2 word operand
      .REF4 longword operand
      .REF8 quadword operand
      .REF16 octaword context

    The .REFn directives are provided for compatibility  with  VAX
    MACRO V1.0.
