Ok, here is what I tried:

.NOLIST
#define   EQU   .equ
#define   equ   .equ
#define   END   .end
#define   end   .end
#include "ti83plus.inc"
.LIST

     .org 9D93h
     .db $BB,$6D
StartProg:
Conditional:
      ld a,3
      cp 7
      jp z,IsSeven
      cp 3
      jp z,IsThree
      jp nz,IsNoneOfThese
IsSeven
	ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHell
      B_CALL(_PutS)
      ret
txtHell:
	.db "7",0
IsThree
 ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHel
      B_CALL(_PutS)
      ret
txtHel:
	.db "3",0
IsNoneOfThese
 ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHello
      B_CALL(_PutS)
      ret
txtHello:
      .db "Hello World",0 
.end

and it didn't work, so i also tried this:

Code: [Select]

.NOLIST
#define   EQU   .equ
#define   equ   .equ
#define   END   .end
#define   end   .end
#include "ti83plus.inc"
.LIST

     .org 9D93h
     .db $BB,$6D
StartProg:
Conditional:
      ld a,3
      cp 7
      jp z,IsSeven
      cp 3
      jp z,IsThree
      jp nz,IsNoneOfThese
IsSeven
	ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHell
      B_CALL(_PutS)
      ret
IsThree
 ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHel
      B_CALL(_PutS)
      ret
IsNoneOfThese
 ld a,0
      ld (CURCOL),a
      ld a,0
      ld (CURROW),a
      ld hl,txtHello
      B_CALL(_PutS)
      ret
txtHello:
      .db "Hello World",0 
txtHel:
	.db "3",0
txtHell:
	.db "7",0
.end

TASM (i haven't tried with the doors CS DSK) always gives an error: unknow command: B_CALL(_PutS)

Try adding this:

Code: [Select]

#define   B_CALL(xxxx)    .db $EF \ .dw xxxx

stevon8ter · « **Reply #2 on:** March 23, 2012, 10:21:18 am »

Ok, I'll try, and does it has to be in the TI83 inc file or in the sourcefile?

Ok, i've put it in the included file, my conclusion: it was there, but in b_call en not B_CALL

Xeda112358 · « **Reply #3 on:** March 23, 2012, 10:24:59 am »

It can be in either

stevon8ter · « **Reply #4 on:** March 23, 2012, 10:51:32 am »

Ok, and what if I wanted an user-input that asks for a number? What B_CALL should it be? Or is it something else?

Ok, in asmin28days, they're talking about this

Code: [Select]

.module    ConvDec8
ConvDec8:
    LD    C, 0

_Loop:
    CALL  GetChar
    CCF             ; End if no more characters
    RET   NC

    SUB   '0'       ; Throw out all characters below '0'
    JR    C, _Check

    CP    10        ; Throw out all characters above '9'
    CCF
    RET   C

    LD    D, A       ; Save value in D
    LD    A, C       ; Load running total
    CP    26        ; Halt if there would be an overflow (260+)
    JP    NC, Ungetc ; Return gotten character

    LD    E, C       ; Save current number in case of overflow
    ADD   A, A       ; Multiply by 10
    ADD   A, A
    ADD   A, C
    ADD   A, A
    ADD   A, D       ; Add gotten character

    LD    C, A       ; Halt if overflow (256 to 259)
    JR    NC, _Loop

    LD    C, E
    JP    Ungetc

_Check:
    CP    ' ' - '0' ; If a space is encountered exit without error
    RET   Z
    SCF
    RET

but in what register is it saved?

Ans I get an error: with : GetChar and Ungetc

Xeda112358 · « **Reply #5 on:** March 23, 2012, 10:58:47 am »

It isn't usually that easy to do in assembly

As for the routine, that converts a string of tokens to a number and stores it to register a (it isn't an input routine). If I have time later, I will write some code for an input routine, but it is not too simple.

Also, avoid double-posting unless it has been about a day and your question wasn't answered (you can just use the edit button).

EDIT: Those calls aren't there in your code, that is why you get an error

Ok, thanks, but as I allready mentioned, I'm a N00B

But I'll try to do the whole 28days.

But usually I like it to get a bunch of examples and then some explanation with it.

Like in this one http://www.arasian.com/support/education/tutorial&t=2&s=9

Euhm, guys, what's the best vti to use to test my progs?

Euhm, other question: why does this gives a RAM clear?

When the processor jumps to Numb1, Numb3, or Numb7, it will load A with the appropriate number, but it will continue, not only to the next LD (if there is one), but also past the end of the program. At that point, it's no longer your code that's executing, and the processor's going to encounter something that leads it to crash.

stevon8ter · « **Reply #8 on:** March 23, 2012, 02:02:07 pm »

Do you have any tips to fix it?

and what if I place a jump to conditions after the 3 ld's?

It worked

Scipi · « **Reply #9 on:** March 23, 2012, 02:42:45 pm »

You could have a jump back to the conditions (I don't remember much from HotDog's tutorials, but I think you could also just place a ret after each so it automatically returns to where it was before)

Unless I'm thinking of something different...

yeah, basically just add a ret after each of the ld cmds, but make sure to use call instead of jp.

stevon8ter · « **Reply #11 on:** March 25, 2012, 10:36:14 am »

Yeah, with the script I posted it only worked with another jp to the conditionals

Xeda112358 · « **Reply #12 on:** March 25, 2012, 11:24:30 am »

***This does not have anything to do with your code above!***
Here is some example code you can play with:

Code: [Select]

;Get the value in Ans
     B_CALL(_RclAns)  ;Ans→OP1
     B_CALL(_ConvOP1) ;OP1 converted to DE, E→A

;At ths point, A contains the value of Ans

     ld hl,37         ;37→HL
     cp 13            ;If A=13
     call z,SetHLto4  ;Then call the routine
     cp 7             ;If A=7
     call z,SetHLto11 ;Then call the routine
     B_CALL(_DispHL)
     ret
;======
SetHLto4:
     ld hl,4         ;4→HL
     ret             ;Return
SetHLto11:
     ld hl,11        ;11→HL
     ret             ;Return

Does this help at all?

In this case that wouldn't work because he doesn't want to return back to where he was, but rather jump to Conditional.
stevon8ter: your code, as it stands, converts keypresses to values, and uses those values to determine what code to execute. In this case, it would make much more sense just to use the keypresses directly to determine where to jump to execute the other code. (That is, Numb1 etc. and Conditional are unnecessary. IsSeven etc. should be jumped to directly from GetKeyLoop.)

To all of you: thank you, and I'll be a long time offline

going on vacation and have there no intenet.

And xeda: I thank you very much, I like the way you do it, givin an example and I can learn out of it, all people may do that

And sometimes i'll ask for an expelnation
