asign

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Sign of the first operand. The asign argument is the address of
    an unsigned longword containing the first operand's sign. A value
    of 0 is considered positive; a value of 1 is considered negative.

 aexp

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Power of 10 by which adigits is multiplied to get the absolute
    value of the first operand. The aexp argument is the address of a
    signed longword containing this exponent.

 adigits

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    First operand's numeric text string. The adigits argument is the
    address of a descriptor pointing to the numeric string of the
    first operand. The string must be an unsigned decimal number.

 bsign

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Sign of the second operand. The bsign argument is the address of
    an unsigned longword containing the sign of the second operand.
    A value of 0 is considered positive; a value of 1 is considered
    negative.

 bexp

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Power of 10 by which bdigits is multiplied to get the absolute
    value of the second operand. The bexp argument is the address of
    a signed longword containing this exponent.

 bdigits

    OpenVMS usage:char_string
    type:         character string
    access:       read only
    mechanism:    by descriptor

    Second operand's numeric text string. The bdigits argument is the
    address of a descriptor pointing to the second operand's numeric
    string. The string must be an unsigned decimal number.

 csign

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference

    Sign of the result. The csign argument is the address of an
    unsigned longword containing the sign of the result. A value
    of 0 is considered positive; a value of 1 is considered negative.

 cexp

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       write only
    mechanism:    by reference

    Power of 10 by which cdigits is multiplied to get the absolute
    value of the result. The cexp argument is the address of a signed
    longword containing this exponent.

 cdigits

    OpenVMS usage:char_string
    type:         character string
    access:       write only
    mechanism:    by descriptor

    Result's numeric text string. The cdigits argument is the address
    of a descriptor pointing to the numeric string of the result. The
    string is an unsigned decimal number.
