 h-sine

    OpenVMS usage:floating_point
    type:         H_floating
    access:       write only
    mechanism:    by reference

    The sine of the angle specified by angle-in-radians. The h-sine
    argument is the address of an H-floating number that is this
    sine. MTH$HSIN writes the address of the sine into h-sine.

 angle-in-radians

    OpenVMS usage:floating_point
    type:         H_floating
    access:       read only
    mechanism:    by reference

    Angle (in radians). The angle-in-radians argument is the address
    of a floating-point number that is this angle. For MTH$HSIN,
    angle-in-radians specifies an H-floating number.
