Hello World,
I've been messing around with Axe for like a week now, and I am just getting into subroutines. So, I read that parameters get stored in r1 through r16. I have no idea how to access those though. I tried to find an answer on both Google and by using the search function of this site, without any outcome. Of course I can store the values in A through Z prior to calling the subroutine, but don't those use RAM memory?
I hope someone can help me out.

Press Vars, Left, 3 to access r1 to r6 ;)

What do you mean by use RAM memory ? Every variable uses 2 bytes of RAM memory, and r1 to r6 are variables too :)
Also, welcome to the forums, feel free to introduce yourself (http://www.omnimaga.org/index.php?board=10.0) :)

Aren't registers part of the Z80 itself?
But, thanks for your answer :)

Some processors indeed have r1 to r16 registers in asm, but those doesn't exist in z80. r1 to r6 in Axe are pretty much unrelated and are simple variables like A to Z, used to pass parameters to subroutines.

^What he said. You cannot even access registers directly in axe (although many routines use them). The "r" tokens are used in BASIC for graphing.

Since the Asm() command allows you to use native hex code, you can do everything you want in Axe :P
