CBMPrgGen

[ajordison]

As some of you may or may not know I've been working on merging C64PrgGen and VIC20PrgGen into one app, you guessed it, CBMPrgGen.

I've got a framework together and like your opinion on it, basically. Note that it's just a demo of the framework, you can't do any prg genning with it yet!

A few others have already had a look at it and the consensus is a 50/50 split between those who like it and those who thinks it's a bit overkill.

Anyway, please take a look (don't forget to read the readme!) and let me know what you think, either here or at ajordison@yahoo.com

Cheers

I haven't tried it, but I think it's a good idea, so you don't have to make the same updates on both applications in the future.

That was the idea really. It's a pain keeping two apps, which are 99% the same, up to date. Plus it's a good opportunity to give both prggens a lick of paint!

Looks good so far. I like the color you have added to the text. Keep up the great work.

I like the look of this a lot.
I don't think it's overkill in the slightest. Then again, I don't really know what overkill would be - the more user friendly you can make it the better!
Looking forward to the finished product!

Seeing the assembly window reminds me of something I started but will never finish - an editor that instantly assembles what you are typing (with instruction codes and timing displayed). The little demo I did in C# demonstrated to me that it's easily fast enough...

What I mean't by overkill is that I don't want to force people to create projects when all they want to do is throw a quick program together. I think I've covered that with the default project though.

That sounds interesting, how does it cope with branches/jumps etc?

Oh, I see. Yeah, it's pretty quick to get a project started, so I think you're on the right track.

Well, it doesn't yet, but the idea is to keep track of labels and references in a couple of dictionaries so that if a label moves, I update references, or if one changes, I invalidate the references (and write XX in the compiled instructions) and so on.

I have another thing to add to my wish list if at all possible. I want to be able to use the undocumented op codes. At least the ones that don't end in a reset or crash. I know back then they were "undocumented" but today they are well documented.

Just a thought if possible.

I want to be able to use the undocumented op codes.

Excuse my curiosity, but what opcodes do you use and in which context?
I am always eager to learn new tricks despite being an old dog

The only opcodes I have encountered so far are ANC, ASO, AXS and that was in a demo.

[GreyGhost]

Not saying that I would have use for all of them but, a few of them would come in handy now and again. If you are interested in learning about them a quick search of the internet will produce many texts on the subject. My interest was peaked when I was looking over DEC2HEX converter from this thread.

Seeing your name peppered throughout that thread makes me wonder if you are poking fun. While some of those opcodes would do no good to a noob like myself, I'm sure you and some of the others here could find many fine things to do with them. It doesn't have to be a demo to utilize them. It was only a suggestion because they are there, why not try to use them.

As far as the opcodes I use, I use the ones that are available to me. I am unable to use the undocumented ones because Vic20 PRG GEN does not allow them and that is the program I have adopted to start learning assembly language(of course I could add them in using .byte I guess). If I had the ops to choose from I'm sure I would find a use for them eventually.

You got me here. Honestly I did not notice the use of illegal opcodes back then. dec2hex uses "lax" to load A&X at the same time. May save a byte every now and then.

While some of those opcodes would do no good to a noob like myself, I'm sure you and some of the others here could find many fine things to do with them.

No need to be humble, I am a noob myself. I just started learning about disk I/O on the VIC, because in the 80ies I only had a tape recorder.

I have to admit I never used illegal opcodes yet. Recently, I stumbled across the three opcodes mentioned above in a demo and that got me started thinking about possible uses.
But as Mike said in another thread, mostly performance/code size is influenced by optimisation of the algorithm, not a few cycles/bytes saved by tricky code.
That is perhaps the reason why I only found some in a demo where indeed every cycle counts.

@GreyGhost, @Kananga: I made a follow-up in the Programming section, the thread '65xx Opcode statistics, an example'. Maybe we should discuss this matter over there before the thread here gets derailed.
