Hello,

I am using MASM32 assembler. I would like to use DOS and BIOS interrupts in my assembly language program.

Whenever I use the int 21H or int 10H command , the computer hangs up,

I have used the following program code

.386
.MODEL FLAT, stdcall

start : mov ax,00;
mov dx,ax;
int 10h;

end start

The assembly sequence works well in Turbo Pascal, but not in Masm.

Please advise in detail how I can go about programming in assembly, some basic help will do.

Thank you
