I started with my understanding of Garth's proposal, and took it as far as I could, short of writing an actual simulator. I borrowed ... |

| ... that a long jump is jmp (,n+) and a long call is jsr (,n+) In fact, I have already translated over 100 machine instructions from 6502 FigForth to 65m32 FigForth, and so far all except one are 32-bits long! Here's a brief hand-assembled list file excerpt ... the binary translations are NOT correct, ... |

| ... it takes to do it on the 6502. It will be fun to see that shortened to just a few instructions. Okay Garth, I translated your 2?do and 2do to 65m32. It looks like the 65c02 needs 52 instructions in 88 bytes to do it. The 65m32 needs ... [drum roll] ... 10 instructions in 10 words to do what ... |

| ... 65c02 when constantly having to deal with the wider numbers. The names won't need the "2" as in "2do" to get 32 bits with the 65m32 though, as it's naturally 32-bit anyway. 2+loop, the internal compiled by 2+LOOP, has 59 instructions by my count. It would be fun to see what ... |

| ... I was able to cook up an online simulation of 65Org16 and 65org32 by modifying the easy6502 emulator: it just might be worth doing the same for 65m32. Cheers Ed ps. see http://biged.github.io/6502js/ online and the source at https://github.com/BigEd/6502js |

I trust your experience and judgment. Where does it fit. Here, there, at anycpu.org ... ?!?

| ... limit, and end address :5e060000 jmp (,y+) ; from rstack and proceed. This isn't really a fair fight, but it looks like 18 words of code on my 65m32 are doing the same job as about 231 bytes of code on the 65c02. The reason that it's not fair is because the 65c02 is not in its native 8-bit ... |

I've never used awk before, but it doesn't look impossible for me to understand (rather c-like, which I have used). Your source excites me into thinking that I might be able to write a template for my 65m32. But, first things first ... SPECS, SPECS, SPECS!!!
Thanks,
Mike |
