Phoenix Edition v3.1 released!

[SMcNeill]

Wow nice list of improvements. What is difference between shift left / right and rotate left /right?

shifts will drop bits from the end shifted toward. Rotate will carry those bits around to the opposite end.

Thanks, OK left and right shifts mult or divide by 2, what does rotate do?

It rotates the bits left or right in a circle.

For example, let's say my bits are &B10000001.

Rotate left once:
00000011   <-- see the 1 on the far left is now on the far right?  We rotated them in a circle.

Rotate left once:
00000110   <-- everything went to the left, with the last 0 being moved over to the right.


Think of it as a game map...  

SHL says you walk the hero left, until they fall off the edge of the map and die.

_ROL says you walk the hero left, until they suddenly walk off the edge and reappear on the right side of the map.
