Operation: op1 is compared to op2. If op1 is greater than or equal to op2, a jump to addr9 is executed. W is left
holding the result of op2 - op1. If CARRYX is specified, c affects the result. Insert an STC before command to
avoid strange results.

Operation: op1 is compared to op2. If op1 is less than or equal to op2, a jump to addr9 is executed. W is left holding
the result of ~op2 + op1 in command #1 and op2 - op1 in command #2. If CARRYX is specified, c affects
the result. Insert a CLC before command #1 and an STC before command #2 to avoid strange results.
