Algorithmic conditions, and returns????

[IcarusLives]

But if what's in my head is correct, then XOR would return BOOL= 0 during this case.

Correct.

Code: Select all

set "XOR(b1,b2)=((b1+b2)&1)"

The least significant bit is 0 if the result of the addition was either 0 or 2.

But Batch already supports binary XOR, hence ...

Code: Select all

set "XOR(b1,b2)=(b1^b2)"

... would have been easier.

Thank you very much for your help aGerman! I feel rather ignored that I forgot about this. I also appreciate the quick explanation
