    The compare instruction CMP subtracts the two operands but does not store the results. What it does do is set flags, in particular, zero, negative, carry, parity, and auxillary carry, so you can follow up the instruction with a conditional branch or call instruction to perform some operation based on the comparison of those two numbers.....

    what flag is set at the A=B?
    what flag is set at the A<B?
    flag is set to 0 when A=B
    parity flag is set when A>B
    carry flag is set when A<B
    Here A stands for the value stored in the Accumulator..
    njoy.... 😉
