I think the biggest difference between an "IDE" and a "programmer's text editor" is knowledge and control of the whole project & build/run process, which enables resolving cross-file source code references, and debugging the running code through the lens of the source code.

Since even just the ...

I'm not a big fan of IDEs; but I would certainly encourage having things optional. For example, I do not like syntax highlighting (except when I write html), and I would want to turn it off. Same with auto-indent.

Most of what has been discussed so far is really about programmers' text editors ...

For multiple editor panes, Excel, Visual Studio, etc already do this by allowing you to drag a splitter bar to have 2 views into the same file. That way you're looking at 2 portions of a large .asm file at the same time, each in their own scrollable area, each can edit with their own cursor. Emacs ...

There should be keyboard shortcuts to jump to the label under the cursor, too, instead of just the mouse. Also, back/forward navigation for any of that sort of jumping around. Maybe bookmarked locations as well that you can use with something like Ctrl-0 to Ctrl-9.
On my to-do list.

An undo/redo ...

I can't speak for others, of course, but I want my source code text large, easy to read and in strongly-contrasting colors. I've yet to see a GUI-based IDE that has those features.

BTW, what do operands such as \2 and \3 mean? It's not any type of assembler notation with which I am familiar.

You ...

I've been working on an IDE that I'm writing in C++. It's specifically designed for my own needs. I was thinking that others may want a fast, self contained (no install required) IDE too. Attached are some screenshots of what I use. However, I'd like to hear what you guys would like to see in an IDE ...

Sorry John. I edited it. Thanks for your answer.

I'm putting in a few BRK instructions here and there for debugging. What I want to do is print a debug message to the screen and then exit the program. However, brk clears the screen. How can I just drop out of my program and leave the screen contents intact? Re-vector the interrupt routine maybe?

I didn't care for lemon64. That's why I made an account here. And going by the help I've received I made the right choice.

(It might be a good idea to put, say, [C64] in a topic title if it's a C64 specific topic. There are a host of 6502 systems and projects of interest here, and many of us are not primed for machine-specific questions.)

You can go back to your head post and click "Edit" and change the title ...

Noted.

Thanks guys. And thanks for your patience too.

After reading many tutorials, I'm at something that I haven't seen in one.
See the attached photos. image2 is the sprite and image1 is how the sprite looks on the screen.
What am I missing?

Can't you just do


_validate_1 ; left, right, down
ldy #0
cpx ch_left
beq _valid
ldy #2
cpx ch_right
beq _valid
ldy #4
cpx ch_down
beq _valid
jmp _invalid

Damn. Yes I can. That never occurred to me. I'm still in the C++ mindset I guess so the "simple" things here are, for now ...

Here's an example...


_validate_1 ; left, right, down
cpx ch_left
php
ldy #0
plp
beq _valid
cpx ch_right
php
ldy #2
plp
beq _valid
cpx ch_down
php
ldy #4
plp
beq _valid
jmp _invalid

Y needs to be used in the next section. If I do it this way then I can avoid many, seemingly ...
