asm string

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Summary:

creating an asm program using hex that takes the ans variable and stores a string in ans.

asm string

jnesselr 21 Jul 2008 14:46

The asm program would have to be completely in hex. It also has to be able to add strings to it.

.nolist
#include "ti83plus.inc"
.list
.org $9D93
.db $BB,$6D
    b_call(_rclans)

I don't exactly know the code, but it would have to be in hex. That way, you could add a string using a simple template.

If you need more information, just ask me.

what do you mean it has to be in hex? All assembly programs are in hex.

And what string does your program store to ans anyway?

Re: asm string

The reason I said it had to be in hex, was because I wanted to be able to simply go into the program editor, see something like:

asmprgm
EF5C6143C9

and be able to add on to the end like:

asmprgm
EF5C6143
EF5E6743C9

It would work like:

1:asm(prgmASMPRGM

So basically, all I need is the starting hex codes.

Then, I would have a template like:

EF41C3(string code here)54

Last, but not least, I would need a way to convert the string to hex codes for the asm program:

character	equate
A	E1
B	E2

That doesn't exactly have to be what it equates to, but that is just an example. To make it simple, we could just make it equate to the token value.

I might be wrong, but it looks like what you're asking for is an overly complicated way to run assembly code in hex from a string?

If not, you might be more clear if you told us what you want to use the program for.

Not quite. The assembly code would take a number in ans, and recall a string in str1.

Re: asm string

DarkerLine 21 Jul 2008 19:02

Oh, I see. You're using an assembly program to give yourself extra storage space for strings.

It's not a good idea, though. You can do the same thing equally well with TI-Basic with one string and a list of indices into it.

Re: asm string

jnesselr 21 Jul 2008 19:32

good idea or not, I sill want to do it. Can you help me, please?

Re: asm string

DarkerLine 21 Jul 2008 21:36

Sure. Here you are:

AsmPrgm
EFD74AEFEF4A21D3
9DB72808477E23B7
20FB10F9575FE513
237EB720FAEBE5E5
21CE9DE7D73803EF
C64F21CE9DE7E1EF
27431313C1E1EDB0
C904AA000000

After this, enter the strings encoded as tokens, with 00 after each string. To keep the code relatively simple, I ignored the possibility that 00 may be part of a valid 2-byte token, so your string cannot include any of: [A], L₁, Pic1, Str1, ZXScl, Sequential, npv(, or setDate(. I don't believe this is a major limitation, if it is let me know.

Edit: forgot to mention - the strings are numbered starting at 0, and there can be at most 256 of them.

Where do I insert the string and how?

Re: asm string

DarkerLine 22 Jul 2008 15:46

Like I just said: insert the string AFTER that code and followed by 00:

AsmPrgm
EFD74AEFEF4A21D3
9DB72808477E23B7
20FB10F9575FE513
237EB720FAEBE5E5
21CE9DE7D73803EF
C64F21CE9DE7E1EF
27431313C1E1EDB0
C904AA000000
<string 0>00
<string 1>00
<string 2>00
...

Re: asm string

jnesselr 22 Jul 2008 15:53

Do I insert the token for the quotes?

Re: asm string

DarkerLine 22 Jul 2008 15:56

Not unless you want quotation marks as part of the string.

Re: asm string

jnesselr 22 Jul 2008 16:00

When I ran it, it said syntax error.

Re: asm string

DarkerLine 22 Jul 2008 16:02

If you ran it using Asm(, the only possible cause is a typo on your part where you added a symbol that wasn't 0-9, A-F, or a newline.

You are really getting into this new contest aren't you? :D

Are you talking about the program challenge #3

Re: asm string

builderboy 22 Jul 2008 16:10

Yep. I can't wait to see your game intro!

Re: asm string

jnesselr 22 Jul 2008 16:27

Actually, this program goes with my movie maker, but I guess I could use it on the intro.

According to the rules, I could use it.

Re: asm string

builderboy 22 Jul 2008 16:34

Movie maker? On a calculator?

Re: asm string

jnesselr 22 Jul 2008 18:27

yes. Also, I am going to make a new thread for suggestions.

If you have any suggestions or things that you want to see in the program, just tell me here.
