Experiment Name: Write an assembly language program to find the smallest element from an array.

Objective:

          (i) To know about several command in the Assembly language.

          (ii) Input a Character.

          (iii) Output a Character.

Source Code:

.model small

.stack

.data

          msg1db0dh,0ah, “smallest element is:$”

          arraydb5,9,6,7,1,3

          smallestdb?

.code

main proc

          mov ax,@data

          mov ds,ax

          lea di,array

          mov cx,5 ; 5 times count

          mov al,[di] ; memory location send ‘di’ registerar data ‘al’

          mov smallest,al

          step:  ;level

                   inc di

                   mov bl,[di]

                   cmp smallest,bl

                   jlel1  ;jge= jump gratherthan equal ,

                   mov smallest,bl

          l1:

                   loop step

                   add smallest,30h ; integer to character (add30 for asii value)

                   lea dx,msg1

                   mov ah,09h

                   int 21h

                   mov dl,smallest

                   mov ah,02h

                   int 21h

         

          mov ah,4ch

          int 21h

main endp

end main

Input/output:

          SMALLESTELEMENT IS: 1
