[org 0x0100]

  

      mov ax , [arr]

      mov si , [size]

      mov dx , 1

      mov bx , 2

findLargest:

   mov cx , [arr+bx]

   add bx , 2

   add dx , 1

   cmp ax , cx

   jl  valuePlace

cmpCounter:

   cmp dx , si

   jnz findLargest

  

   jmp resultPlace

     

valuePlace:

      mov ax , cx

      jmp cmpCounter

     

resultPlace:

      mov [result] , ax

     

      mov ax,0x4c00

      int 0x21

  

arr: dw 7,3,10,6,15

size: dw 5

result: dw 0
