Ordinal Numbers Using Pascal

   As I learned computer programming my first programming language that I have learned is Pascal the compiler that I am using during those days in college in Turbo Pascal 5.0. In this program I would like to reminisce the past by writing a program using Pascal as my programming language to accept a number from the user and then convert the number into ordinal equivalent values. In this sample program I am using Turbo Pascal 5.5 that is widely available right now to download free from any charges over the Internet. This problem I encounter during my college days in our programming class.
