You ought using 4x4 font like in BBC Basic and store as ASCII, not TI tokens.

One idea of mine is an oncalc debugger. No kidding, it is possible to a certain extent.

Features that I have though:
- disassembler (already done in Calcsys but I suggest using 4x4 font for displaying more code)
- hex editor and memory viewer (again implement 4x4 font)
- view registers upon On+otherkey token (I have seen this done)
- breakpoints (just do a call to the debugger)
- call the debugger with a odd key combo

Good luck with the project. The main problem is memory issues on source code and labels, memory will be a limitation... Macros would be though and I only suggest implementing simple ones in later stage.

that would be nice. Just make sure to add the CalcSys author permission (or check the license if it's required) to include code from it, though.

he still pops in in #ti sometimes, though. I saw him sometimes. He's a math teacher now (like Critor and Mic on TI-BANK). However idk if he still checks his ticalc e-mail address anymore.

You could always use CalcSys to do this, but I don't think I will natively support it.

Sure!
Make sure you have CalcSys installed (duh ) and run it.
Press 6, then 1 to open the VAT menu.
Press 1 again to get the program list.
Choose the program you want to look and push the corresponding number.
Press Alpha+D to disassemble, Alpha+H to view the hex.

Yes.

Nope, not unless you write a customized program in assembly.

Don't forget that you don't need BB6D or ret from Axe.
