hi. can someone give me a link with a tutorial on how to make graphics using the turbo assembly language? graphics like square, circle, lines, etc. thanks

Have you tried ths?

Your 16-bit assembly program can not call any of the win32 api graphics functions so you will have to bite the bullet and write it all yourself. I would suggest you get Turbo C graphics library and learn how to call those functions from your assembly program.

xor ah,ah
mov al,0x13
int 0x10

Graphic mode?
