Product of Two Numbers Using Function in Pascal

I wrote this program using Pascal to ask the user to give two numbers and then the program will compute the product of two given numbers using functions in Pascal. I am using Free Pascal as my Pascal compiler in writing this program. Free Pascal can be downloaded free from the charge on the Internet.
