Okay, so I've been working on this for a while now, and I'm pretty happy with how some of my routines are turning out so far. I haven't gotten very far, and I'm still only working on the very basics of it right now, but here's basically what I'm thinking about:


zIDE was inspired by Deep Thought's XDE, but this will be for on-calc Assembly programming. If it ever gets done, here's what I'm planning for it to have:

• Custom text editor
• 4-level grayscale syntax highlighting
• Line numbering
• Line auto-indenting
• Jump to label / Jump to line
  
• Relative label support
• On-Calc Compiling with fairly descriptive errors (as much as possible, at least)
• Running
• #include support (hopefully)
• Saving as a program that can be edited in the normal OS editor
• Back-up to AppVar

   Note: If #include support ends up working, I will make the ti83plus.inc file a separate file so the app doesn't take up a huge amount of pages. However, the ti83plus.inc file will definitely not be the complete file. I will try to include as much of the basic things as I can, but I doubt it will include things like the two-byte key codes (of which there are A LOT).

Honestly I'm not sure how many pages this app will end up being, but it shouldn't be more than two...Hopefully I can get it all into one page.

So, that's what I'm planning. We'll see how much I can actually get to, seeing as I'm basically learning ASM as I go with this thing. I already feel like this has been such a great learning experience!

Right now I'm working on the text input, so nothing stated above is absolutely positively for certain going to happen, but that also means that it can change and be added to! Any suggestions are welcome (in fact, I'd LOVE suggestions to make it even better).

ALSO, I will be asking a lot of questions, and probably have a lot of routines that I'll screw up little things in (or maybe big things) that might need some debugging, so any and all assistance is also welcomed with open arms.

I may have a screenshot pretty soon, but that's all for now!

I noticed a while ago that the routine supplied in 28 days doesn't account for partial matches. There are also a few other errors in some routines...

i like FPS games and i can program in TI BASIC language. I want to learn Axe or ASM programming

If TI-BASIC is the language you're most comfortable with, then I'd suggest learning Axe first and then ASM. Axe is pretty much the perfect combination of TI-BASIC and ASM for people who want to ease into assembly programming.

Personally, I really like the name Eliza (or Elisa, however you want to spell it). Also the name Kit (as a nickname for Katharine).

NOOO!! This was looking so good!!

You can use this page, too. On the left you can see the bytes, and cycles are there under the heading "T". However it doesn't seem to have the number of cycles for most of the undocumented commands.

I have a program that uses two buffers and it toggles which buffer it's writing to using a flag. Because it uses that flag I figured it would be a good idea to utilize that for drawing routines so they can draw to whichever buffer it's currently set to instead of having to have separate routines for each buffer.

While writing those routines, I came up with this set of rectangle drawing routines that I think are pretty good, though they probably could be optimized quite a bit.

Anyway, I thought I'd share them:

Honestly I'm not sure that these routines are even the best way to do it, but I feel they're pretty good. If anyone has better routines that I could swap these for, then I'd love to see them!

EDIT: Thanks to Calc84maniac, the bugs have been fixed and it now works properly!
