Agreed. I would love to be able to work with Axe while I'm away from my computer.

Axe is quite great. The only thing is that it doesn't do floating points so doing math programs in it could be hard. You can use a mix of Axe and BASIC, though. Also with Axe you must backup often due to RAM clears (If a program got errors, it doesn't give an ERR message, it crashes like ASM)

If you want to be technical, you can use Floating point in Axe, but it's really difficult with the Axioms disabled.

Hmm you mean an Axiom to do floating point? I wonder if it could be done using hex code instead for now?

Yeah, you can do anything you want with hex. Anything... >:D

There's a float{ command in Axe too, but it can get confusing.

It's already confusing. What's a floating point?

Let's see, quick explanation: In ASM, numbers are generally either one-byte or two-byte. This means that you have a range of 0 to 255 (or -127 to 128 signed) or between 0 and 65535 (or -32767 to 32768 signed). More importantly, they're all integers. You can pretend that a two-byte number has one byte of decimal values (it's called fixed-point notation; you can find more info in the topic about the ** command), but really, you're still dealing with integers. But since a graphing calculator would be pretty useless with just integers, TI uses a notation called floating-point. It involves one byte telling you the exponent, one byte telling you the real/complex stuff, and seven bytes for the actual number for a total of nine bytes per floating-point number. (Each byte can hold two digits in binary-coded decimal, so that's why your calc gives you 14 digits of accuracy, if you've ever wondered.)

You really don't need to know this for Axe, so don't worry if you don't understand it. I suck at explaining stuff anyway.

At least it gives me a starting point to look it up.

In ASM, never use floating points to store data. It's slow and huge. It's mostly suitable for high-precision math.

I will keep that in mind.

Also, would those who have tried out Multitab please post with their thoughts on the program? I'd like to hear what you think of it.



edit: 2/7 of Chemitab has been saved to my laptop thus far. Just so y'all know.

Cool to hear you did backups. :D It's essential for any project IMHO.

Sadly I didn't test, though, since I've been out of school for several years and do not use math programs anymore. I might check later for the interface and stuff, though.

When the code gets onto my computer, that's when the code is in a format I can upload to share with y'all. The real backups are the stuff I write by hand on paper.

Just so people don't start thinking I've finally made to the 21st century or anything...

Ah ok, well, paper-based "backups" also do the job pretty well.

I don't think I would like to recopy 120 KB of code by hand from a game like Reuben Quest 2 if I lost everything, though. O.O

I would have to agree with you on that.

I've almost finished writing the code for Chemitab, just have to finish one last subprogram.


edit: finished!
