We will be entering lots of 'experimental' code in this page and will not be using it in Page 8. Be sure to save it as Page7 so that we don't mess up Page6. When you start a program, such as MicroWorlds or Word or Excel, you usually double click on an icon. This is an instruction to the operating system to look on the hard drive and find the program that is associated with the icon.
Memory is the place where programs are stored and and where they live as they are running.
This is the RAM that you buy when you buy your computer and there are millions of places, each with an address, where the program and we as programmers, can store things. If we want our program to store a number, we can tell it to. But if we want to use the number later or change its value, we need a way to tell the program which storage place we are talking about. So we use names. When we want to create a storage place to hold a value, we give it a name.
