The signal names are shown in the standard 6502 block diagram
Yeah, sorry about that. I was preoccupied when I first read your post and only got about half the information. I do think it would be useful to have put a link to that block diagram in the post for morons like me. I realized right after ...

Re: 6502 ALU pseudocode
You may want to explain your selection of names. I don't think are common/standard. The DAA input(?) seems like it may have come from 8080 land. But it may just be me; I'm not an '02 guru. Nevertheless, this page linked to on the front page of 6502.org may be of some help:

Re: Building the "Perfect" Programming Language
I should clarify one thing that I said a couple times. When I say "self hosting" I mean that the compiler RUNS on and generates code for the same machine. It does NOT necessarily mean that the compiler is BUILT on that machine or that it can build itself on that machine or even that it is written in ...

Re: Cowgol programming language
That's a really nice piece of work! I personally think Ada is underrated and should be used more. I hope to get some time to play around with Cowgol in the near future. It looks pretty interesting.

Re: Building the "Perfect" Programming Language
I would guess that it's a good idea to include recursion and local variables, partly from a perspective that this is good way to improve structure and maintainability of some kinds of programs, and partly because it might help your language look attractive to someone experienced intending to help ...

Re: Building the "Perfect" Programming Language
Agreed. Our brains don't all work the same way, and what is the "perfect" programming language for one person, won't be for the the next.
Absolutely. it won't even be perfect for me! Hence the quotes in the title. I'm already mostly decided on what the language should look like (somewhat like a ...

Re: Building the "Perfect" Programming Language
(I'm sure you won't get any kind of majority view here - so whatever interesting views you do get, you'll do best (I think) if you continue to follow your own vision.)
Following my own "vision" is certainly the intent. If you design a language by committee you end up with horrors like PL/1 or ...

Building the "Perfect" Programming Language
This thread has already spawned one other thread and now has prompted me to start this one. Although discussing religion and politics at the same time is probably safer than "best" programming languages, I will nevertheless dive right in.

Re: C in a uC... what were they thinking??
Right, that is a skill we should all try to develop. The problem is that that will never be enough for you to outperform an optimizing compiler on larger programs. On modern processors, it does all of those things better than you can.
People keep making this assertion like it's a religious mantra ...

Re: C in a uC... what were they thinking??
Recently, I had the job of taking over someone's prototype development, and part of the system included C code to read RAW data from an SD card. Having recently written my own SD card code for the 6502, I figure it would be an easy project to do. It took me only a few hours to get SD access on the ...

Re: Choosing a microcontroller
How do you choose which family of microcontroller to use?
Purchasing tells you what you can use. Unfortunately I'm not really joking. But given our choice, most of the engineers I work with have a few things they consider important. These are probably the most common, but the order varies by ...

Re: HES FORTH for VIC20 available?
WOW! I had no idea it would be that much work or I wouldn't have asked. I really do appreciate it. Now I have to put it to good use to make your efforts worthwhile.
Thanks,

PS I booted it up in VICE and it seems to be working just fine.
