Phoenix Edition v3.1 released!

[Kernelpanic]

Good job again! Nullo problemo!

The bit rotations are similar to the shift operators, where is the concrete difference?

Rotate vs Shift (qb64phoenix.com) -- See if this helps explain the difference. 

Very well explained! And graphically too! 
It was already clear to me that ROR/ROL works like a kind of endless chain - but both shift and rotate of them should work the same way up to the end of the chain, right?

It's still easy with 8 bits, but what about 64 bits? A normal computer can no longer reach this limit, unless I can set this limit. So, eight bits is the limit. Anything beyond that will crash or disappear in a game.
