Although Grade Point does not have a Save menu item on its main menu, it does have a Save As menu item. (See Database Concepts for the reason that Grade Point lacks a Save menu item on the main menu. You will find a Save menu in some of the other areas of the program, such as the progress reports window.) Most programs have both Save and Save as, and it is important for users to understand the differences between them.
The Difference Between Save and Save As
Save As presents a dialog box that allows you to select where you want to save a document and what you want to name it. Save works behind the scenes because it already has that information.
The First Time You Save
Select Save or Save As if you create a new document and it has never been saved before. It doesn't matter which you select in this case, because you're going to get the Save As dialog box regardless of your menu choice.
Subsequent Saves
Use Save if you edit a document that has been saved before. In this case, Save will replace the older copy with the newer copy without bothering you about where to save it or what to name it.
Changing the Name or Location
Use Save As if you want to save a copy of a document in a different location or you want to save a copy of a document using a different name.
