How do I properly save a file in prolog so that it saves to

How do I properly save a file in prolog; so that it saves to the file with the owl icon (it keeps creating a new file with a ~ symbol at the end). This makes no sense to me. How do I get the compiler to recognize my saved database (I keep getting an error where it won\'t recognize the rules that were made before saving). How do I compile a database in emacs without creating a new seperate file? The emacs editor won\'t do the same features with the .pl file as with the .pl~ file, why is this?

Solution

Ok. You have nothing to worry about the file with the extension ~, as long as the original file has been created. Actually, the file with ~ extension is a buffer which will store the data, and the current data, as long as the file is OPEN. If the file is not open, you can see that the other file with extension ~pl will not be seen.
