Or with Stack (ORS)
The ORS instruction is a 32-bit instruction that logically ORs the
value in the accumulator with the first level of the accumulator
stack. The result resides in the accumulator. The value in the
first level of the accumulator stack is removed from the stack and
all values are moved up one level. Discrete status flags indicate
if the result of the ORS is zero or a negative number (the most
significant bit is on).
