Introduce Yourself! / Re: Here I am!

Hmm?  Peanuts?  Rick Astley?  (And also, The Game?)

Are these sort of like memes?

Will there be a test?

Introduce Yourself! / Here I am!

Hi - I'm a (soon to be) 10th grader living in the US.
I got interested in my TI-84 around January when I discovered (*gasp*) you can program these things!
I intrepidly googled, then came across a bunch of tutorials (tibasicdev.wikidot.com, mostly).  I made my first quadratic solver, then never looked back.
Since then, my grades in school slowly started to drop (except math), and my backpack grew significantly lighter (because I stopped checking out so many library books).
Around this June, I started getting tired of the limited graphics in BASIC, then started exploring Assembly, and then the Axe Parser.  Heehee - Axe is fun!  (Sprites!  Speed!  Grayscale!)
I'm planning on making a bunch of arcade games right now - and maybe an RPG later, if I ever figure out a unique plot.

Axe / Re: A few simple questions...
« on: August 10, 2010, 12:37:42 pm »
Okay, so to summarize...
If I do 5->A, the calculator will create a (temporary?) variable, and store 5 to it?
And if I do 5->{A}, the calculator will go to location A in the RAM and overwrite whatever was there then store 5 to it?
And I should avoid using curly braces except for L1 and L2.
Stick to strings and appvars, because the other data types are weird.
Am I right?

Also, I have several more questions:
3) How much is a byte?  I think nemo said that 1 byte can hold up to 255, so would that mean that 1 byte is equal to 2 hexadecimal characters? (like FF would be 1 byte?)
4) DJ Ommimaga said that there are about 712 bytes of space in L1 (and probably L2) - so I would use those two if I wanted to construct a list of some kind?
5) What are the differences between the variables A-Theta and using Str, Pic, and GDB?  Is it safe to use curly braces around those?
6) I think curly braces are used primarily for creating lists in safe RAM spaces - my numbers would be in sequential order.  Is that correct?  What other things can pointers be used for?

Axe / A few simple questions...

Hi - Axe is great, isn't it?  I just discovered it last week.
I have a few questions though:
1) How do pointers work?  I think I understand the basic concept, but I'm not entirely sure what the difference is between doing this
Code: [Select]
5->A and
Code: [Select]
5 ->{A}2) Also, I tried using the routine in the User's Manual to try to copy an external variable, but I keep getting this weird sort of hexadecimal thing
Code: [Select]
"varG"->Str1
GetCAlc(Str1)->P
Disp {P}[sup]r[/sup]>DEC          (The triangle with the DEC to the right)
And this gives me weird values - especially if I try storing decimals, large, or negative values to G.  Am I doing this wrong? 

I apologize if any of these questions are stupid...  :(
