Writing to hard disk

[nurul]

Hi all,

I have a small assignment that my lecturer gave me about writing an array into memory in hard disk or floppy disk. Can anybody help me because i'm just learn assembler.
Thanks..

nurul,

Its a very simple task but members will not do your homework for you. Tell us what you have learnt and what you are learning and someone may be able to help you. Is it 16 or 32 bit assembler ? Is it for Windows or for DOS ?

here's a list of API functions that you will find useful:
CreateFile  (create/open a file)
WriteFile  (write to the file)
CloseHandle  (close the file)

Sorry...
I'm doing it for 16 bit in DOS. I found out we can use int 13H . can it be implemented?

OK,

You must have some course guidelines to work by, which assembler and how much do you know so far.

   mov ah, 0ah                                ; and then storing it in a string named appnd
   lea dx, appnd
   int 21h
   mov ah, 42h                          ; this the part where i am facing the problem
   mov bx , handle                     ; i am workingaccordingto the steps given in the norton guide
   lea dx, appnd                        ; where ah = 42h the function, ds:dx the offset from the start<<< i think this the mistake
