Function
« on: July 02, 2012, 06:43:14 pm »
I just wanted a further explanation of this:

Data(NUM,...)
Key: ΔList() 
Adds the bytes to program memory. Numbers ending with r are added as 2 byte numbers.

You have to point your liste of data. Eg :
Code: [Select]
:Data(2,5,100,40,3)->Str1
You can read those data in this way :
Code: [Select]
:{Str1}
:.Return 2

:{Str1+1}
:.Return 5

...

:{Str1+X}

If you want add a 2-bytes number, you can use ^r (2nd angle 3) :
Code: [Select]
:Data(12,500^r,200,30000^r)->Pic1

:{Pic1}
:.Return 12

:{Pic1+1}^r
:.Return 500

:{Pic1+3}
:.Return 200

:{Pic1+4}^r
:.Return 30000

Endeed a byte is 8 bits. Then a byte can take 2^8 (=256) values, that to say a number beetwen 0 and 255. A 2 byte number can take 2^16 (=65356) values, it means a number beetwen 0 and 65355.

Axe variables are 2 bytes number.

Thanx this really helps.

Do you know about anything about numbers bigger than 65355? Are they 3 bytes or 4 or something like that?

You can combine 2 real variables or use the OP registers...
Due to dissatisfaction, I will be inactive on Omnimaga until further notice. (?? THP hasn't been much success and there's also the CE. I might possibly be here for a while.)
If you want to implore me to come back, or otherwise contact me, I can be found on GitHub (bluebear94), Twitter (@melranosF_), Reddit (/u/Fluffy8x), or e-mail (if you know my address). As a last resort, send me a PM on Cemetech (bluebear94) or join Touhou Prono (don't be fooled by the name). I've also enabled notifications for PMs on Omnimaga, but I don't advise using that since I might be banned.

Combine how ? and what are OP registers?

Depends on how much bigger than 65355.
My projects
 - The Lost Survivors (Unreal Engine) ACTIVE [GameCommandoSquad main project]
 - Oxo, with single-calc multiplayer and AI (axe) RELEASED (screenshot) (topic)
 - An android version of oxo (java)  ACTIVE
 - A 3D collision detection library (axe) RELEASED! (topic)(screenshot)(more recent screenshot)(screenshot of it being used in a tilemapper)
Spoiler For inactive:
- A first person shooter with a polygon-based 3d engine. (z80, will probably be recoded in axe using GLib) ON HOLD (screenshot)
 - A java MORPG. (pc) DEEP COMA(read more)(screenshot)
 - a minecraft game in axe DEAD (source code available)
 - a 3D racing game (axe) ON HOLD (outdated screenshot of asm version)

Basically, to know the limit of X bytes, you do 2X*8-1.
So 1 byte stops at 255, 2 bytes stop at 65535, etc :)

The OP "registers" are a set of memory areas that are used as operands by the OS's floating point routines. Unless you need floating point, there shouldn't be a need to explicitly deal with them.
If you want to do math with larger integers, you basically need to write the routines yourself (precluding a library/axiom already having been written. I don't follow Axe too much.).
For example, to add the number BA (formed from variables A and B) to DC, and store the result back to BA, you could do something like A+C->A<C+B+D->B, where -> is the STO> symbol.
An easier-to-follow variation goes like this:
Code: [Select]
A+C->A
If A<C
B+D->B
Else
B+D+1->B
End

By the way, the r in the description is the radians r (it's in the [2nd][Apps] menu)
