Bitwise NOT, is this getting "opposite" colors???

[CharlieJV]

If you use "PUT" graphics statement with XOR mode. So the image could always be seen, although weird sometimes.

You've lost me.

Are you saying the XOR in PUT does the same thing as what these Bitwise NOT's are doing in my sample code?

If so, I think I'm going to need some help understanding how that can be.
