Hey guys is there a way to edit axe programs on a computer? My program is over 15000 bytes and its a pain to scroll to the bottom every time. I already have an emulator on my computer to run the program, i just need to know how to edit the whole thing in a large document in order for me to program it faster.

I recently made a mega-post of every good Axe coding tool I know about. Here's an excerpt that should interest you:

Thank you! And since this is a Q&A I will be asking a ton of questions lol. Is there a hex code or command in Axe to receive the amount of ram left currently on your calculator and store it to a variable? Thanks in advance.

feel free to ask

if you have bigger problems or questions make a new thread in the axe subforum.
with asm() you can insert these hexcodes (called asm opcodes) into your programm. I think the asm code you need is

Code: [Select]

asm(EFE542EF9247EF5641EFBF4AC9)store the value to a variable and display it as a decimal:

Code: [Select]

->A
Disp A›Dec

I wrote this from my mind and I'm don't know whether this is correct. (but I think so)

also here is a list of some asm codes, but watch out the tutorial isn't about axe:http://tibasicdev.wikidot.com/hexcodes#toc52

thanks! this helped a lot!

That looks like a snippet intended for use by a BASIC program. In Axe, the snippet becomes much simpler, as it's just the system call with no wrapper logic needed: Asm(EFE542).

for the axe use of asm codes look here: https://www.omnimaga.org/ti-basic-language/zeda%27s-hex-codes/60/

I have some questions about random numbers in axe:
1) how do I seed the random numbers generator?
2) once seeded will the rng always return the same stream of numbers?

Sorunome · « **Reply #1853 on:** April 30, 2015, 08:02:16 am »

You, as in the programmer, doesn't seed the random number generator, that happens automatically.

If two seeds were to be identical then, yes, the number stream would be the same
EDIT: Trust Runer on this, i just used basic comp sci knowledge to answer, to which that timer would theoretically count towards the seed
EDIT2: Just listen to Runer

You could theoretically set the seed, as the seed value does exist at a fixed location in memory. But this is relatively pointless, because...

No. Axe's PRNG is not deterministic, as it uses both a time source and a pseudorandom memory read as sources of entropy for every number generated.

This has always bothered me, really... would people be interested in it being replaced with a deterministic PRNG?

Well I might need it for a sandbox game prototype ime working on. You now, seeds.
But yea thanks

I don't understand what the r1 pointers (found under the vars>polar menu) are used for

Those are the variables that function arguments are stored in. For instance, Func(A,B,C) is effectively syntactic sugar for A→r₁:B→r₂:C→r₃:Func().

Two questions
1) how many cpu Cycles does it take to read a byte from a file like {y1}
And doing exp》{y1} automaticallysagves it to the appvar that very instance right?

About 200 cycles. For reference, it only takes 14 cycles to read a byte from RAM. So if you're going to read this data often and are worried about speed, you should consider migrating this data to RAM.

Is 》 supposed to be →, the store operator? In that case, I hope Axe would throw an error if you tried to compile that, as you cannot (for most intents and purposes) write data directly to archive.

Combining your two questions together, it sounds like you're planning on doing many read/write operations to an appvar. In that case, you should probably UnArchive it to work on it and Archive it when done.
