## Code for Program that reads a digit, computes and prints 'P' if it is positive, 'N' if it is negative and 'Z' if it is zero( Simulation of switch-case statemt) in Assembly Language

``` .MODEL SMALL
.STACK 100H

.DATA
PROMPT  DB  'Enter the digit : \$'
MSG     DB  'The entered digit is : \$'

.CODE
MAIN PROC
MOV AX, @DATA                ; initialize DS
MOV DS, AX

LEA DX, PROMPT               ; load and print PROMPT
MOV AH, 9
INT 21H

MOV AH, 1                    ; read a character
INT 21H

MOV BL, AL                   ; save the input character into BL
