Matrix  db 0,1,2,3,4,5,6,7,8,9,0Ah,0Bh,0Ch,0Dh,0Eh,0Fh
QDM     db 4;Matrix dimension

, each line mov al,[edi];Output [edi] means print. I did not implement it because I do not know what compiler and OS do you use.

I use assembler 8086. by which interrupt I should print the result ??
mov ah, 02h
int 21h ?? or something else?????
Thanks for your help

Yes, you can use it.

I tried one more time, but doesn't work.Your post is all right and helpful for me
If you can help me one more time it would be grateful. I couldn't print the result. tnx

I work on Windows 7. It does not allow to use interrupts, so I can print using Windows API only. Is it fine for you?

The AL(Assemly Linker) task wraps AL.exe, a tool that is distributed with the Windows Software Development Kit (SDK). This Assembly Linker tool is used to create an assembly with a manifest from one or more files that are either modules or resource files.
