Can someone be so kind as to show me how these commands work in relation to setting flag bits and checking to see if a variable has a certain flag set?

Thanks in advance.

These involve binary numbers, where each digit is known as a bit.

%bitand applies the AND test to each bit of two numbers. If the bit is 1 in both numbers, it will be 1 in the result. Otherwise, it will be 0.

%bitor applies the OR test to each bit of two numbers. If the bit is 1 in either number, it will be 1 in the result. Otherwise, it will be 0.

%bitxor applies the XOR test to each bit of two numbers. If the bit is 1 in one number and 0 in the other, it will be 1 in the result. Otherwise, it will be 0.

%bitnot applies the NOT test to each bit of one number. If the bit is 1, it will be 0 in the result. Otherwise, it will be 1.
