Well, I've been inactive on these forums for a while, but not on the calculator.  So this is what I've been doing: a BASIC shell.

Of course its not all BASIC, I've needed an ASM program for 4 functions:
 1: Number of programs on user's calculator
 2: Getting the first couple bytes of each program, for use with text sprites
 3: Getting the name of each program
 4: Running the selected program

The startup is a little slow (due to archiving variables such as a copy of the user's graph screen), but other than that it actually works really well so far.  It not only saves all of the settings it changes, but every single real/cplx variable!

The setup should be familiar to anybody who has a computer (except the lack of a mouse), using 7*7 text sprites for icons (an unrolled loop, if you're wondering how it draws them so fast).  It currently does not support running programs (need to figure out how to do that, but I do plan to allow ASM programs as well), archived programs with icons in the source code, or selecting programs that do not have icons.

Grr. Wabbit won't play nice with this.  First, my GetProgName function fails in MathPrint mode (returns Str1="mean(", fixable, but annoying), then my icons all have that row missing, I forget how to fix that.  It initializes slower on my calculator, due to the presence of 32 programs on it.

Is there supposed to be a missing line in the each sprite?

I was too lazy to just paraphase....

Oh yeah! Thanks for noticing holmes.

oh, I was just looking at the pretty screenie.

It looks nice reminds me a little of my old CCI shell project, but not as feature filled, although faster. I guess there is a trade off for not using Celtic III and making it more dynamic
I hope you have lots of fun with this project

Oh it's probably nowhere near done... getting it to run programs will be the fun part though. (unless I dump the program name to another program...)
But yeah, most of that speed during boot is because of Wabbit's instant-write flash.  I do quite a bit of archiving on boot. (Pic, GDB, 28-item list)

Yeah, I don't know about that line... Never happened to me on the actual calc until just after I transferred it to the computer. Then, next time I ran it, it garbage-collected and that seems to have fixed it.
Then again, I did just replace the batteries before transferring... ?

Anybody have any ideas for how I can keep a more permanent index of programs? My current method is by index in the VAT, and, needless to say, extremely volatile. Also, I'd rather not use Str2 for permanent icon data...
