Now, that is definitely cool, but we can go further. But with OLE it retains its nature as a spreadsheet, so you could change on of the numbers on the slide and have the calculated result change, just as if you did it in Calc! If what you had on the slide was nothing more than a static picture of the spreadsheet table, you could not edit it. You could, for instance, have a group of cells and use them to calculate a result. So instead of just being a static object it is alive in the slide. So the first level of OLE utility is that if the object is in a slide but is recognized as a spreadsheet object, you can edit it on the slide using the Calc editing capabilities, and get it to do spreadsheet functions. A great example comes with spreadsheets, since you create them in a spreadsheet program like Calc, but you might want to take a table created there and put it into a slide to display. What it means is that you can use data from two different programs together, and changes made in place are automatically reflected in the other place. This was developed by Microsoft, but has spread to the free software world as well. The next topic we want to cover involves something called OLE, which stands for Object Linking and Embedding.
