I've finished about half of these, so far. And on Monday I think I'll do a couple more.
Here is an example of using DEBUG:
1. Open notepad
2. Copy and paste in this code:
Code: Select all
a 100
mov si, 0
mov ah, 09
mov dx, 300
int 21
mov ah, 3f
mov dx, 200
int 21
jmp 120
a 120
mov cl, [200+si]
cmp cl, 20
jl 160
add si, 1
jmp 120
a 160
mov byte [200+si], 24
mov ah, 09
mov dx, 320
int 21
mov ah, 09
mov dx, 200
int 21
mov ah, 02
mov dl, 21
int 21
mov ah, 02
mov dl, 0d
int 21
mov ah, 02
mov dl, 0a
int 21
mov ah, 09
mov dx, 340
int 21
mov ah, 08
int 21
int 20
a 200
a 300
db 'What is your name: $'
a 320
db 'Hello, $'
a 340
db 'Press any key to continue . . .$'
rcx
399
n hello.com
w
quit
3. Save the file to your desktop as "hello.asm"
4. Open up the Command Prompt
5. Type in "cd desktop" and press enter
6. Type in "debug < hello.asm" and press enter
7. DONE!
Now just look at your desktop, and you should see a "HELLO.COM" file on your Desktop. Double click it, and see something like this:
Code: Select all
What is your name: john
Hello, john!
Press any key to continue . . .You may think this code looks extremely difficult. Well, actually, it's not. That's why I'm starting these tutorials, so people can learn Assembly and how to use the DEBUG command to write COM files.
