Could we host it on here? That would be nice, in case eem's server crashed and he lost it. It might be the only copy left!

Er... his host is still up for me. I can browse ASM In 28 days mirror fine. Freehostia just have crappy uptime when it comes to free hosting (as they say, you get what you pay for )

one question: when getting the variables r1 to r6 from the input, in what order are they received?  Is HL holding r1, and the rest are in order after that in the stack?  Or is it r6 in HL and opposite order in the stack?

Axioms don't use r1-r6. r1-r6 are actual memory locations, like the A-Z vars, while the arguments of a function (that's what you're talking about, right?) are stored in this way:

The first argument is deepest in the stack, the second the second deepest, etc. Then the second-to-last argument is on top of the stack (first out), and the very last argument is in HL. As an example, say you have a function nDeriv(:

nDeriv(0,1,42,1337,9001)

When the Axiom routine takes control, 9001 is in HL. Doing a POP HL puts 1337 in HL; POPing again gets 42, then 1, then 0.

Thanks DT

also, how do subroutines work?  Do they allow for more than the 255 byte limit of routines?

What kind of subroutines? sub( subroutines in Axe, Axe command routines (such as for DispGraph), or Axiom subroutines?

no, in an axiom quigibo states that you can have your normal assembly code for your axiom routine, but he also mentions subroutines applying to the regular routines (but without much explanation).

Wait, where is this?

Oh, I see. It works like this:

First of all, an Axiom is a definition for a command (which you know). You could define nDeriv( to run a custom routine, for example.

Axe lets you choose whether you want your Axiom to exist as subroutines at the end of the program instead of being inserted in each place where the Axiom is called.

For example, say that routine you wrote for nDeriv( takes up 300 bytes. It would be extremely inefficient to stick that 300-byte code at every point nDeriv( is called in the program, so you tell Axe to make this a subroutine that goes at the end of the program (like sin( and DispGraph) that gets CALLed at every point nDeriv( appears.

Whereas if you have a different command that does something really simple (like in 2 bytes), you might as well not make it a subroutine and instead stick those two bytes wherever it's called.

It's no longer on freehostia, although freehostia will redirect you It's now on eeezor.ec3club.tk which is much faster

thanks quigibo never thought to look there for the updates

also, congrats on making the axiom system!  I'm extremely impressed on how it works -- yesterday I got an 8 level grayscale one to work.  It's so easy to make and use Axioms -- I LOVE it!
