I've looked at a bunch of different programs and a lot of them use bytes explicitly.
I was just wondering...
How would a TI-BASIC programmer use these bytes?
What would I use them for?

Could you break it down to a level a noob (well... ASM noob) could understand?

For example, Builderboy was talking about how he used bytes in Portal X to do something...

Any clarity on the topic will be greatly appreciated.

Do you know how hexidecimal works?

What do you mean?

If I said, what does 0A represent, you would say...

It looks like a memory address... Or 10 in Base-10.

There you go! So, when you do this in Axe:
[010203
it stores three bytes to the end of the binary. They are as follows:
01
02
03
Who'd a thunk?

So, let's say you do this:
[010203->GDB1
Then, when you do this:
{GDB1}->A
01 is stored to A.
Also, if you do this:
{GDB1+1}->A, you get 02 stored to A. Kapeesh?

Oooooohhh. I get it. So, how would you store more than that to something?

Instead of [010203, do [01020304

Raylin · « **Reply #8 on:** March 23, 2010, 02:10:06 pm »

I mean, how do you have Axe extract more data than just those two values?
Instead of just 01, how do I make it take 0102 and evaluate it?

SirCmpwn · « **Reply #9 on:** March 23, 2010, 02:15:35 pm »

{GDB1}^r->A
Puts 0102 into A

Raylin · « **Reply #10 on:** March 23, 2010, 02:18:09 pm »

So, 01 is actually one byte... And 0102 would be two bytes...
This means that everything involving bytes would be in hex.
Correct?

SirCmpwn · « **Reply #11 on:** March 23, 2010, 02:18:30 pm »

Yes.

*EDIT*
Unless you do
5->{GDB1}

Raylin · « **Reply #12 on:** March 23, 2010, 02:24:09 pm »

What happened there?
Are you allowed to drop the zeros?

SirCmpwn · « **Reply #13 on:** March 23, 2010, 02:25:39 pm »

Not hex

Raylin · « **Reply #14 on:** March 23, 2010, 02:26:32 pm »

Ahh. That would make sense.
Axe allows you to access all memory to store data...
