While Loop Statement in Turbo Pascal

In this article I would like to share with you a sample program to demonstrate how to use while loop statement using Pascal as our programming language. I am using Turbo Pascal For Windows as my Pascal compiler in this sample program. What does the program will do is to display a series of number from 1 to 20. I hope you will learn something in this simple program that I wrote. Thank you.
