Yeah, they're still bitwise, just now they're only 8 bit instead of 16 bit.  Have you tried compiling?  It should still work if you were only using low bits.

well you can use the stat plot draw types to do the full 16 bit AND/OR/XOR i belive, so you should only have to change the original commands to the new ones.

I'm not going to make a separate version because I need to keep consistency with the new version.

The XOR thing you were talking about, the efficient way is simply this: 1-{L6+A}(r)->{L6+A}(r) since adding one to the negative is the same thing as the complement.  I think I will have the not() command do this more efficiently in the future though.

Im not quite sure what 1 byte means, but i can say what bitwise operators are.  You know how normal operators work?  Like OR AND and XOR?  they take two numbers that are either 1 or 0, and outputs a number that is either a 1 or a 0.  This is how everything works in TiBasic.  Well, if you want to do it bitwise, you can do some complex things:

Any number can be represented in Binary

5 = 00101
3 = 00011
and so you can AND/OR/XOR the individual bits of these numbers together.  For instance, of you wanted to OR 5 and 3:

5   Or   3   =   7

0   OR   0   =   0
0   OR   0   =   0
1   OR   0   =   1
0   OR   1   =   1
1   OR   1   =   1
So using a bitwise OR, 5 OR 3 = 7.  It doesn't make much sense at all by looking at it in decimal, it only makes sense once you actually go into binary.

Still unsure what it means. I am used to have stuff for example like (A=2) and (Y=5) and used in If conditions, giving true (1) or false (0)

Oh well I guess all I'll be able to do is try it out and mess around

I'm a visual person so I won't get it otherwise

aaaah ok ^^

I doubt I will use a lot of low-level stuff myself. The only thing I might use is reading/writing bytes from/to the RAM or stuff like that

That's really, really cool!  I like it. It's turning into a really epic game!
