I'm pretty sure this topic fits here.
I'm working on tutorial for Grammer. I worked until chapter 4.

Any criticism/suggestions? (But not on the web design please.
I just used a template. If my webpage looks bad, blame the template XD)
There is still the trouble with Chapter 4 since the logic expressions are actually not like TI-BASIC (they perform bitwise logic). Since I am pretty sure you know sprites, think of it exactly like that. Also, they use the full 16-bits of the instruction. In cases where you are using just Boolean logic, though it works fine
With that, I want to look at this:
Quote:
So 3=5 and 7>3 will return 0, and 3=5 or 7>3 will return 1. Also, !3=5 will return 1.
The first one:
3=5 and 7>3
3=5 and 1
3=1
0
That is correct, but not based on the way you presented it.
3=5 or 7>3
3=5 or 1
3=5
0
And that one doesn't work :/
EDIT: Oops, I forgot to present how to fix that. The easiest way is to use the colon
Code:
3=5: and 7>3
3=5: or 7>3
Since colons are allowed in If statements, these are really useful. They pretty much take the place of parentheses. In both cases they start with 3=5 which returns 0. That is then passed to the next section of the math:
0 and 7>3
0 and 1
0
0 or 7>3
0 or 1
1
Hmm, that's interesting. So Grammer doesn't use grouping parentheses for logical expressions at all?
Unfortunately, not :/ It reads them as just another math operation.
