Ok I have a feeling I'd be able to firgure this out myself, but it would prolly take a while since I don't remember much from math

Anyway, so I have a projectile flying at (S,T) with an angle, Z.  If Z is zero it faces straight down, 256 degrees, etc.
I have an enemy at, say, (X,Y).  How would I check which side of the projectile the enemy is on (right or left), related to the projectile's angle?

tan⁻¹(S-X,T-Y)-Z^256<128 should be true if the projectile needs to rotate in the positive direction.
tan⁻¹(S-X,T-Y)-Ze0 is optimized but returns the opposite.

Check out MemKit (it comes with axe).

Because it's not 2015 yet.

Why doesn't everyone use linux?

Check the length field to make sure it is right. If you put a label at the end of the axiom, you can use that in the length field. Also make sure that the axiom ends with dw 0000.

First of all, if the axiom is a program in ram, then axe will automatically convert it to an app var the first time something is compiled that uses it (assuming the appvar doesn't already exist).

On the other hand, here is an axe program that should do what you wanted:
GetCalc("prgmAXIOM")→A
GetCalc("appvAXM",{A-2}ʳ)→B
Copy(A,B,{A-2}ʳ)

Edit: Oh yeah, and here is a mimas include file that has the same equates as Axe.inc.

L₁→Str0 and GetCalc("Str0",Y₀) refer to two completely different Str0's. Assuming you want to get L₁ into Str0, as in if you were to type Str0 on the home screen, it would display the string at L₁, then:
Copy(L₁,GetCalc("Str0",length(L₁)→L),L)
