NASL(580) shifts D (the shift word) by the specified number of binary bits
(specified in C) to the left (from the rightmost bit to the leftmost bit). Either
zeros or the value of the rightmost bit will be placed into the specified number
of bits of the shift word starting from the rightmost bit.

Operation
ON when the control word C (the number of bits to shift) is
not within range.
OFF in all other cases.
ON when the shift result is 0.
OFF in all other cases.
ON when 1 is shifted into the Carry Flag (CY).
OFF in all other cases.
ON when the leftmost bit is 1 as a result of the shift.
OFF in all other cases.
