MY GAD (not about jebus, read?)

[Atari-Jess]

I think I finally am beginning to understand ASM!

 

*begins to cry*

 

its so... beautiful!

 

I only have JUST started to figure out how its working

so dont expect me to be like, making stuff...

thats crazy talk.

 

But ASM really is a wonderous thing... My full respect to all the ASM coders

especially the ones that had to work with 6507 code.

 

Just cheer me on, and ill keep going. its only taken me a year or so

just to "GET IT" let alone start doing anything at all.

 

*sigh* Gotta love the computer

[Happy_Dude]

ASM?

Whats that?

 

j/k

 

Keep it up.

You'll be tearing you're hair out in no time

[Sir Plus]

Congratulations! But temper that knowledge with patience.

 

Computers are actually very stupid, and the 65xx processor can only do one thing at a time. So try not to tackle everything at once, but break everything down to tiny steps.

[Atari-Jess]

someone got the letter b to show up on the screen today.

I wanted an asterix, but B is close enough for me.

 

This is only going to take a few years.

 

yay....

[Happy_Dude]

What processor are you programing for?

 

I know a little x86 ASM and its really easy to print strings.

(just don't ask me how it's been 2 or 3 years since I did it )

[Atari-Jess]

trying for both x86 and 68k

but x86 to start.

 

I need to use that TASM and Tlink program or at least

something similar but perhaps better

because the one that i have is pretty lame and i dont like it

since it doesn't work.

 

Instead of the million of lines of code for the 6502 to display a letter

it took like 5 lines of code for the x86? geez... One day ill tackle

that 6502 but that will be years upon years upon years upon years

from now. being that years till i figure it out, years till i get good. years to

do other stuff and then years to decide to move on to 6502

[Happy_Dude]

I have a couple of billion disks to search through,

but I'll post some TASM code for strings when I find it.

 

If you're not using tasm you should be able to port it

easily enough as I like to HEAVILY comment my code

[Happy_Dude]

.EXE Hello world

DOSSEG

.MODEL SMALL

.STACK 200h

.DATA

.CODE

Message db "Hello World$"

START:

mov ax,cs              ;cs points to code seg or message

mov ds,ax

mov dx,offset Message

mov ah,9

int 21h                ;print dx 

mov ax,4c00h

int 21h

END START

.COM Hello world

 

MAIN    SEGMENT BYTE

       ASSUME  CS:main,DS:MAIN,SS:NOTHING

       ORG     100H

Message db "Hello World$" 

START:

mov ax,cs  

mov ds,ax  

mov dx,offset Message 

mov ah,9 

int 21h

mov     ah,4CH

mov     al,0

int     21H             

MAIN    ENDS

END START

 

Hope this helps

I had TASM and Tlink for a little bit but i lost em any place i could get it and all the other files ill need again? i have to use debug and its not as good!!oor at least a similar program that is compatible with it.

 

and did i get banned from the stella group? i never even said much there.... i dont get messages from them anymore

 

anyone know? i used my hotmail account...

[Happy_Dude]

Try Kazza

Or Google it, Free assemblers are everywhere

Contact Russ Perry Jr ([email protected]), he is administrating the group now. I don't think you got banned. What was your name on [stella]?

[Lumpbucket]

Whoops! Double post...

trying for both x86 and 68k  

but x86 to start.  

 

x86 to start? YUCK! x86 is the second most completely horrible assembler i've used (i can do 6502, 6809, Signetics 2650, 68000 - 68060, PowerPC, x86 and i'm a professional Z80 programmer). I think you'll find 68k MUCH easier to learn from scratch, and MUCH nicer, too. I learnt 68k first and its still (by far) my favourite.

[Atari-Jess]

I need to get me some ASM books....

[cschell]

I agree. Start with the 68000 and not x86. The register set is much friendlier as I recall.

 

As for displaying text, that really has a lot to do with what else is in the system. If you can put text on a screen with a few lines, there's some other device making your life easy. The individual processor just feeds the graphics chip.
