You can compile all of these in one go. Click Actions on the menu then Make All (or just press the F5 key). This should whizz through and compile the lot in under a minute. You can view the IDE Log window. If you want to save this window, right click on it then click Save As.
The Image shows the log after compiling.
If you make the same mistake as I did, and click Window/Cascade on the IDE menu, you'll end up with a diagonal stripe of minimised windows. To find the right project, click Window then (right at the bottom) More windows...
On the next page : Make and run an Application.
