 complex-base

    OpenVMS usage:complex_number
    type:         F_floating complex, D_floating complex, G_floating
                  complex
    access:       read only
    mechanism:    by value

    Complex base. The complex-base argument contains the complex
    base. For OTS$POWCJ, complex-base is an F-floating complex
    number. For OTS$POWCDJ_R3, complex-base is a D-floating complex
    number. For OTS$POWCGJ_R3, complex-base is a G-floating complex
    number.

 longword-integer-exponent

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

    Exponent. The longword-integer-exponent argument is a signed
    longword containing the exponent.
