I like the way you think Deep Thought ;) IMHO if we are going to be doing such complicated things that we are coding in half asm and half axe at the same time, maybe it would just be easier to code in straight asm or add in some small hex codes for small things

Although then it cannot be used in future contests :P (unless they're not pure-Axe-only)
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

The problem with Asm( is that it's difficult to read hex, while reading ASM is much simpler in comparison. Just my opinion ;)
Maybe I should just wait for Mosaic at this point, though mixing Axe and ASM would be nice.

Right now, I'm using OTBP to assemble short ASM clips into hex, then using that for Asm(. It actually works pretty well.

If native registers were supported, it would only be the most basic use of the registers: loading, adding, subtracting, and shifting, plus maybe a few simple things I'm not thinking about.  It would only allow things that are legal in asm so you wouldn't be able to add b and c and store the result in d.  Don't forget that part of implementing the 8 bit mode is moving the variables close enough to relative reference with IY so there are more optimizations possible.

By the way, I'm taking an assembly class using MIPS architecture (very similar to ARM) which feels like such a higher level language compared to z80.  Those instructions are specifically designed to translate from C compilers and only now do I realize why there haven't been many good assemblers for z80 so far :P.

Nice Quigibo! And Yeah, the calc using a 8 bit processor doesn't help much x.x. I heard it was much easier to code in ARM assembly than z80, for example.

THose optimizations and features sound great :D Im especially excited for 8 bit mode ^^

Hey, I have another idea for register access. How about using Greek letters, like α for register A, β for B, γ for C, δ for D, ε for E, and σ for F (since it kinda looks like a "flag" anyway ;))? If someone's so good with calculators that he wants to use the native registers, he can probably access the restricted tokens pretty well.

Those are pretty hard to access, though. It would be best to choose tokens that are available without having to use a 3rd party program, even if it means renaming ANOVA( to A (slightly modified to stand out from the regular A) or the like

Maybe he could use the X[NUM]T tokens, but replacing them with the greek letters. In that case, flags could be replaced with that weird serif'd F.
