Chapter 5: Standard RLL Instructions - Logical
Or with Stack (ORS)
1
The Or with Stack instruction is a 32-bit instruction that
230
logically ORs the value in the accumulator with the first level
240
of the accumulator stack. The result resides in the
2
accumulator. The value in the first level of the accumulator
250-1
stack is removed from the stack and all values are moved up
260
3
one level. Discrete status flags indicate if the result of the Or
with Stack is zero or a negative number (the most significant
DS Used
bit is on).
