I know in Dictionary program we can search any word and find meaning but in my project I want to add some words with their meanings (before execution). when program run it ask the user to enter the word for search meaning of that pre-defined word that is already saved( maybe in array of string or any file).when user enter the word program search that word and display that word with meaning to user if exist otherwise it says not found..

here is my code help me please to find meaning

.model small
.stack 100h
.data
CLASS DB "Aftab","Ahmad"
DB 'Hello','gbolo'
