Write an assembly language program to display the string “microprocessor” using 16-bit microprocessor code. Assume any necessary data.

model small

·         stack 32h

·         data

string db “microprocessor$”

·         code

main proc

mov ax, @data

mov ds, ax

mov dx, offset string

mov ah,09h

int 21h

·         exit

main endp

end main

Program Analysis:

‘data’ creates an array in the memory. ‘db’ is specified for 8-dit data manipulation ‘string’ is the name of array. ‘$’ represent the end of array element. ‘@’ is used to send the address of array in ax. Since the address of each array element is not same ‘offset’ defines the different address for different element and send it to dx.

‘’mo\v ah,09h

int 21h” is the syntax to display the string.
