will this code work for my project??

This is "THE DIGITAL CODE LOCK" Program which takes a 4-digit password
;from the user and compares it with the already saved password.
;If the password entered is correct then the LED GLOWS!!!!
;$ THE DOOR OPENS!!!!
;Otherwise if the password entered is incorrect then the message - "INCORRECT CODE"
;is displayed on the screen of the LCD.
;PIN P0.7 an LED is attached which glows as the lock opens!!!
