; Example usage of the imul instruction in amu 8086
; This program multiplies two 16-bit numbers (300 and 400) and stores the result in DX:AX registers

.MODEL SMALL
.STACK 100h

.DATA
multiplicand DW 300
multiplier DW 400

.CODE
MAIN PROC
    ; initialize the DATA segment
    mov ax, @data
    mov ds, ax

    ; load the multiplicand and multiplier into AX and CX registers, respectively
    mov ax, multiplicand
    mov cx, multiplier

    ; perform the multiplication using the imul instruction
    imul cx

    ; store the 32-bit product in DX:AX registers
    mov dx, ax
    mov ax, 0

    ; return to the operating system
    mov ah, 4Ch
    int 21h
