That looks to me as if it would work pretty well. Have you given it a try yet? Tthanks for the interjections, Lionel.
ACagliano are you gonna make your tutorial on this? I think I read something on the IRC, is it true? I'm looking forward to it.

Oooh, I hope he will! If he does, everyone wins, I think.
I am starting a tutorial on game design using Axe, yes. It will delve into everything my TI-Basic version did, and then will address using CalcNET as a linking protocol.

Oh that's great

Not read on z80 architecture, but I'm pretty sure there are no "free" cycles during the duration of any one instruction...unless you start talking about pipelining or hyperthreading... o.o
Were you worried the buffer might be read between storing the high and low bytes?

Axe usually uses
Code:
push HL
; get pointer into HL here
pop DE
ld (HL),E
inc HL
ld (HL),D
except when it's a constant location; in that case it uses
Code:
ld (ADDRESS),HL
Oh, I see. I'm also not too familiar with Axe. If Axe has a word load instruction, I can't imagine it would compile into two two-byte loads. But if Axe has only byte load instructions, you might be right, and that wouldn't be very desirable.
Are there any good Axe tutorials on the web aside from just the Axe documentation?

kindermoumoute's writing a very complete tutorial on the Site du Zéro (it's in French).
I'm working on an "Ultimate Guide to Axe Parser" on my own site, as well as a few specific tutorials on arrays and making a SHMUP in Axe.
Progbeard, so Deep Thought did indeed confirm my concern. Personally, I'd stick with ASM if you feel proficient enough in it, but I'm slightly biased. ACagliano, what were you saying earlier on SAX about having to move around memory?
Hey, everybody! I have an *UNTESTED* CALCnet axiom for you guys! It's only the source, as I can't compile right now. Here it is:

Here's how an Axiom works:
1. In Axe, place an #Axiom() token (where AsmComp should be in the Catalog) and put the compiled Axiom name in the argument.
2. Use these tokens in the program:
- CoordOn starts CALCnet, CoordOff stops CALCnet.
- Xmin, Xmax, and Xscl are pointers for the send buffer's target, data, and size, respectively.
- Ymin, Ymax, and Yscl are the same for the recieve buffer.
- Delta X and Delta Y are the second bytes of the size words. You can read them and write to them as you would in ASM (set and clear the high bit).
EDIT:
I'm not really an ASM programmer. I thought that all the addresses needed a 0 in front of them.

Only the ones that start with a letter. There are two accepted formats: $F02C/$89E2, or 0F02Ch/89E2h.

I get what you are saying Kerm, so we are clear on that.
I'm just confused. I don't believe Axe uses little endian, so in Axe, it may be 0x80[size]. Maybe you can tell me Kerm,
if I had to flip the memory high and low bytes of the Cn2 calls and the memory areas from the standard z80 conventions in order to use them in Axe, I should have to flip this as well, correct.

If you are using z80 hexcodes, you are using little endian. However, in Axe, the pointers are 2 byte values, so you don't have to worry about it - it manages it for you. The only note I need to make about this Axiom is that you must store or read 128 to the Delta ("Frame Ready") values.
Compynerd, here's your program compiled as hex, in case it helps you at all:
