        !             3: ldiv \*- long division
        !             4: .sh SYNOPSIS
        !             5: .ft B
        !             6: ldiv(hidividend, lodividend, divisor)
        !             7: .s3
        !             8: lrem(hidividend, lodividend, divisor)
        !             9: .ft R
        !            10: .sh DESCRIPTION
        !            11: The
        !            12: concatenation of the signed
        !            13: 16-bit
        !            14: .it hidividend
        !            15: and the unsigned 16-bit
        !            16: .it lodividend
        !            17: is divided by
        !            18: \fIdivisor\fR.
        !            19: The 16-bit signed quotient is returned by
        !            20: .it ldiv
        !            21: and the 16-bit signed remainder is returned by
        !            22: .it lrem.
        !            23: Divide check and erroneous results
        !            24: will occur
        !            25: unless the magnitude of the
        !            26: divisor is greater than that of the high-order
        !            27: dividend.
        !            28: .s3
        !            29: An integer division of an unsigned
        !            30: dividend by a signed divisor may
        !            31: be accomplished by
        !            32: .s3
        !            33:        quo = ldiv(0, dividend, divisor);
        !            34: .s3
        !            35: and similarly for the remainder operation.
        !            36: .s3
        !            37: Often both the quotient and the remainder are wanted.
        !            38: Therefore
        !            39: .it ldiv
        !            40: leaves a remainder in the external cell
        !            41: .it ldivr.
        !            42: .sh BUGS
        !            43: No divide check check.
