Triangle Pattern in Turbo Pascal

In this article I would like to share with you a sample program that I wrote using Pascal as my programming language. It will create and generate an triangle image using asterisk symbol on the screen. By the way I am using Turbo Pascal 6.0 for DOS as my compiler in writing this sample program.  Thank you very much.

Multiplication Table in Pascal

I there for couple of days I was not able to upload new tutorial because I don't have available internet connection at home for the moment. Anyway this article I would like to share with you how to create a multiplication table using Pascal as our programming language. I am using Turbo Pascal 6.0 for DOS as my Pascal compiler in this sample program. What does the program will do is to generate multiplication table using for loop statement in Pascal. I hope you will find my work useful. Thank you very much.
