Code:
     ld hl,0         ;loading 0 into hl (gives it the number to start at)
     ld b,100      ;loading 100 into b (gives it the number of loops)
Loop:       ;label
     xor a       ;stores 0 into a (that's the row/col i want to display on)
     ld (penRow),a     ;loading a into penRow
     ld (penCol),a      ;loading a into penCol
     VDispHL      ;display the contents of hl
     inc hl       ;increase hl (goes to next number that i want to display)
     djnz Loop      ;run the loop (not too sure how to elaborate)
     ret      ;exit the prgm



That's what I know (or think i know)

DJNZ decrements B, and jumps back to the label specified if the Z flag isn't set.

Oh, ok. Sweet





*My programs are NEVER finished
Or, if you work better with mnemonics: Decrement and Jump if Not Zero. Decrements B and if B is not zero, jump to the label following. Note, that you can only DJNZ 128 bytes forward and backward from the current location.

Ok. The code doesn't work, though. It compiles, but when I run it, nothing displays. And then the program ends...





*My programs are NEVER finished
I completely forgot to say something earlier. I just checked and VDispHL is a DCS call. So, instead of bcall _VDispHL it is call VDispHL. Sorry for the confusion. I'm surprised your program didn't crash, though.
http://tanner.myserverathome.com
Here is the code I am using....


Code:

.nolist
    #include    "ti83plus.inc"
    #include   "dcs7.inc"
.list
.org    $9D93
.db    t2ByteTok, tAsmCmp

   ld hl,0
   ld b,100
Loop:
   xor a
   ld (penRow),a
   ld (penCol),a
   call VDispHL
   inc hl
   djnz Loop
   ret

.end


It displays "33941", and then it froze. My calculator has crashed...





*My programs are NEVER finished
Before you do the call VDispHL, you need to save the B register and the HL register from being overwritten. You can do this with push BC \ push HL \ call VDispHL \ pop HL \ pop BC.

Edit: You forgot the entire DCS header Razz

To start off, you are using DCS to run this program, correct? After that, you aren't using the DCS header. Here is a slightly modified (smaller, without the pretty stuff like descriptions, icons, and ALEs (not needed here)).
Code:
.nolist
#include "ti83plus.inc"
#include "dcs7.inc"
.list
   .org progstart
   .db $BB,$6D
Init:
   xor d
   ret
   jr Start
   
   .dw 0000         ;or .dw $0000 if you don't have a description
   .db $07,$00         ;always this string
   .dw 0000         ;or .dw $0000 if you don't have an icon
   .dw 0000            ;usually .dw $0000 if you don't have or know what an ALE is
Start:                             ;main routines
You would then match up your Start with the Start from this header. (Header was taken from: http://dcs.cemetech.net/index.php?title=ASM_Header#Normal_Header )

Edit: Also, what Souvik said. Don't forget that you pop in the order that you push. In other words, push bc \ push hl \ call VDispHL \ pop bc \ pop hl won't work the way you expect.
http://tanner.myserverathome.com
This is the final (working) code:


Code:

.nolist
    #include    "ti83plus.inc"
    #include   "dcs7.inc"
.list
.org    $9D93
.db    t2ByteTok, tAsmCmp

   ld hl,0
   ld b,100
Loop:
   xor a
   ld (penRow),a
   ld (penCol),a
   push hl
   push bc
   call VDispHL
   pop bc
   pop hl
   inc hl
   djnz Loop
   ret

.end

Because you're using a DCS call, you need to add a Doors CS header to your program, to prevent other shells or the TI-OS from mistakenly executing it and crashing on the VDispHL. You can read about the ASM Header on the DCS wiki, although since you seem to have difficulties with reading documentation, here's a sample:


Code:

.list
   .org progstart
   .db $BB,$6D
Init:
   xor d
   ret
   jr Start
   
   .dw Description         ;or .dw $0000 if you don't have a description
   .db $07,$00         ;always this string
   .dw Icon         ;or .dw $0000 if you don't have an icon
   .dw $0000            ;no ALEs
Start:                             ;main routines
   ;etc etc etc
   ;ret
Description:
   .db "Hello World",0   ;can be omitted if .dw Description is .dw 0000 above
Icon:            ;a 16x16 icon (can be omitted if .dw Icon is .dw 0000 above)
   .db %11111111,%11111000

   .db %10000000,%00000001
   .db %11111111,%11111111
FWIW, I have a shortened header on the page before with the header, though Kerm's is better commented than mine, I believe.

Ah, I didn't see that, thanks for that. Smile Hopefully TI_Coder will see that.
I just recently got into asm programming again, but can't seem to get anything to compile correctly. I am using the SDK. I write "compile.bat count.asm" into cmd under the correct directory. It compiles count.asm into an empty .8xp file. How can I get it to compile correctly?





*My programs are NEVER finished
Does the assembling/linking process seem to throw any errors? If so, can you post them here? If not, can you start by posting the program source in question here?

No errors. Even the example source code doesn't compile correctly. No matter what prgm I try to compile, it turns it into an empty .8xp file





*My programs are NEVER finished
Do "compile.bat count" and make sure count.asm is under the source/ directory. Also, make sure Python is installed and BinPac8x is running.

As Souvik says, don't put the .asm on the end. I believe if you had read the readme a bit more carefully you might have seen that. Wink
Ok, I've written a "Count" program referring back to a previous project. Here is the working code for it...


Code:

; Program Name: Count

   .db "ZALE",0,0,0,0 ;always eight bytes, use
   .db "ZLALE",0,0,0 ;zeros for extra bytes
   .db $FF ;put after last ALE

   call clrLCDFull
   ld hl,0
   ld b,100
   
Loop:
   xor a
   ld (penRow),a
   ld (penCol),a
   push hl
   push bc
   call VDispHL
   pop bc
   pop hl
   inc hl
   djnz Loop
   call getKey
   ret
.end


I really would love to start re-writing PAZAAK. I'm starting to understand the language a bit more than I was able to before. I'm actually retaining information lol

Edit: And yes, I used the "Normal Header" from the DCS SDK





*My programs are NEVER finished
So far so good. Smile Since you're writing a Doors CS program, by the way, you can call Pause, which has fewer side effects than calling getkey. Are you writing for the TI-83 or the TI-83+? If the latter, your two calls need to be bcall()s.
