Nice stuff! HEX programming on the TI-89!

What does it actually DO for you though?

Random memory editing....

Need I say more?

I've been a beta tester for a while and command post has kept me busy during many math classes.

I should have been a beta-tester.... I've been waiting this out impatiently since about April(*) of 2002!

This program will go IMMEDIATELY to my calculator. THANK YOU GREG!!!

(*) Well, from the first month that it was announced, whenever that was.

How does the memory "leak"?

When you dont free allocated memory.

That's why I'm always really careful about using the memory allocation functions.

btw, I like your game Alien Invasion. I got to level 89 :)

Thanks :O)
I think the highest ive gotten to on Alien Invasion is level 150ish.

Aagh! They have ResNet at Georgia Tech? *shudder* I'm sorry... I can sympathize...

Resnet? Hey, that's in your URL...

Oh, about the command post program... does it visually convert the hex code to ASM, or do you have to know hex to use it?

I had another thought... since C code is translated to ASM before it runs on the 89/92+, could I use this to learn how C translates to ASM? That could help me learn it... maybe not, it's just a thought

Version 1.0 doesn't, but i do have a very good start on a disassembler implemented in the current version.

Cool, that's great :-)

I just stay away from memory allocation all together. I don't see any benifit to it anyway.

...is this the same as using saferam?

I don't 100% understand it, but what I think it does, is gathers up memory for you to do memory-intensive stuff later on in the program. Then, you free it when you're done with it. I think it's for preventing memory error crashes and stuff. Am I close to being right, anyone? :)

There is no such thing as "saferam" on the TI-89/92+/V200. You need to allocate all the memory you are going to use apart from the CPU stack.

So if you're coding c and you want to create a file how do you do it without memory allocation?

same way you and I do, unzip you pants and ai... oh, you mean calc memory.
It just allocates stuff incorrectly (i think)

It's when they don't free allocated memory (I think this was answered farther up)

What do you mean by allocated memory? Are variables in it relocated to a new register or address in the RAM chip, and stay there until they are deleted, thus taking up space if they aren't and causing free memory to decline?

This program is a lot like CalcSys for the TI-83 Plus, except cooler!

CalcSystem is Cool!!!

No, just CalcSys. >:| lol

CalcSys is really very useful!

yeah, especially when you get it to delete your operating system!

How do you delete your OS, and what happens to the calculator when that happens?

I don't know how I do it, but it just happens. Then the calc says "Waiting...Please install calculator software now"

Weird. The fact that the calculator can actually display text like that is strange because text functions and characters are defined in the OS itself.

The first 64 KB (on the TI-89/92+/V200 - I don't know the exact quantity for the TI-83+/73) of FlashROM are write-protected and contain the so-called "boot code", which also includes a copy of the fonts.
