I'm using a custom-named variable as a pointer.  In my experience I haven't had to put curly brackets around it like you have to do with normal variables.
How do I modify what part of the ram it points to?  Not the byte itself but the location of it.

Also is it possible to have one-byte custom variables, and if there's a way then putting r after it all the time then how?

As far as I know, if you use a custom named variable, it is impossible to modify the location it points to, as it is treated as a constant pointer.  It is also impossible to have only a single byte custom variable as far as I know.

Would it work to modify the pointer itself then?
(ie if I did L1→oName would modifying {L1}r work)

That wouldn't be modifying the pointer, you would be modifying the byte at L1.  Like I said, custom variables are treated like precompiled constants, so their location is hardcoded into your program and not modifiable.  If you want a pointer that can be moved to point to many different locations, you will have to use a variable as a pointer.

Why does sin(1) return 3 and sin(3) return 11?

What should it return? Remember period is 256 and range is [-127,127].

Axe doesn't use the standard degrees system - it returns a value between -127 and 127.

I went into Essence's source code, and found the part that doesn't work right at 15mHz.
Spoiler For ZSHOOT:
Quote from: code
..
C=2 or or(C=6)?0→E,1→E
{C+GDB0BA}→A

 // Suspecting this line..
!If (getKey(30)+(getKey(31))+(getKey(32))+(getKey(38))+(getKey(40))+(getKey(46))+(getKey(47))+(getKey(48))-1)

U*10+Bul→r1
{C+GDB0BQ}→Q
E*8+X→{r1}r
.X+(8*(C!=2))->{r1}^^r
E*8+Y→{r1+2}r
.Y+(8*(C!=2))->{r1+2}^^r

 // ...or these
getKey(32)*2+(getKey(30)*2)-(getKey(48)*2)-(getKey(46)*2)+(getKey(31)*3)-(getKey(47)*3)→F*A→{r1+4}r
getKey(30)*2+(getKey(46)*2)-(getKey(32)*2)-(getKey(48)*2)+(getKey(38)*3)-(getKey(40)*3)→G*A→{r1+6}r

If Opt
If {Opt}
!If (C=1)+(C=5)
rand^3-1*8+{r1}r→{r1}r
rand^3-1*8+{r1+2}r→{r1+2}r
.SWITCHED^
F*4+{r1+4}r→{r1+4}r
G*4+{r1+6}r→{r1+6}r
End
Else
C!=1*S+{r1+4}r+(rand^3)-1→{r1+4}r
C!=1*T+{r1+6}r+(rand^3)-1→{r1+6}r
End
End
C→{r1+8}
{C+GDB0XP}→{r1+9}
!If C-6
F*9+{r1}r→{r1}r
G*9+{r1+2}r→{r1+2}r
End
!If C-1
{r1+4}r*6+{r1}r→{r1}r
{r1+6}r*6+{r1+2}r→{r1+2}r
End
U++
End
Would there be a way to make this work at Full speed, and keep it somewhat as-is?  (or some more-optimized way :P)

When that code is ran at 15mHz, the keys in some part or another don't detect properly and/or get mixed around.  I've been suspecting key delays, but I'm also told that getKey always goes in 6mHz :/  At 6 it runs fine, but I'll end up using the Full speed.
Also I can't use getKey=# , that messes up when you press an arrow key.

I'm seeing some possible optimizations in the code, but I'm wondering if I'll have to slow it down rather than speed it up to get it to work...

Just try to run the getkey code in 6mhz and see if that works

I've tried that..the keys sort of work but there's some mix-ups between the keys, or the calc thinking there's other keys pressed aside from the normal problems. (ie pressing [sin] and nothing else makes the calc think both [sin] and [^] are pressed)

Is there some operation that can be done inline to slow it down, maybe allow for the delay to do its job (better at least :P)?

Idk, it has to do with reading the port.
