16 bit Assembly Hello World

[Sean3]

Code: Select all

-a 100

XXXX:0100 mov ah,09             ;String Function

XXXX:0102 mov dx,0109         ;Address of 0109

XXXX:0105 int 21                   ;Do it

XXXX:0107 int 20                  ;exit the program

XXXX:0109 db "HelloWorld"   ;Charater to output

XXXX:0113                           ;<return>

-rcx                                    ;edit the cx register

CX 0000
:0113                                 ;File size of our program

-n hello.com                  ;Name of file with a .com extention

-w                                      ;Write the byte size

Writing 00113 bytes
-q                                    ;quit the program

You will get used to it someday. I had trouble first look

any recomendations on a tut on asm?

[Sean3]

I can do a user input tut.

[acerookie1]

I can do a user input tut.

yeah i meant a link to a completely noob friendly version of asm.

[eatcomics]

google works well...

[acerookie1]

google works well...

yeah then i wouldnt be askin here... none of em make them as easy or well explained as i learned c++, c or c#. its really like posted source code.

@Sean3: Are you running XP? Might want to consider explaining the context of your snippet:

Typing those commands into debug.exe (an assembler/debugger included in Windows operating systems before Vista) will yield the executable "hello.com". This is a 16-bit console program that will only run natively on 32-bit operating systems (can be emulated rather easily using DOSBox on a 64-bit OS).

I recommend you take a look at FASM.

perhaps something a bit cleaner.

Code: Select all

.MODEL Small
.STACK 100h
.DATA
   db msg 'Hello, world!$'
.CODE
start:
   mov ah, 09h
   lea dx, msg ; or mov dx, offset msg
   int 21h
   mov ax,4C00h
   int 21h
end start

Yes I'm using winxp, but I'm more used to debug fasm says its a virus with norton so now I'm thinking of getting rid of AV.

LOL.. it's Norton that's the virus. Good luck getting rid of it (I highly recommend a full backup before even considering attempting anything).

[LeonBlade]

Assembly?!?!?! Sounds like a virus!!

leon I love how your pic changes every month :D and also... assembly... like legos right? is what you are thinking leon

Is that site a joke? Or are people THAT obsessive over things.

Ok, I know there are people who are, but is there really an entire website full of them? They think denmark is evil??

EDIT: Not stereotyping religious people, just people who analyze things to such extremes lol.
