Yes, however it's very difficult to constantly be switching back and forth between your block program, and the C editor. It gets confusing as you can't edit some of the files (globals.c?), and if I primarily want to program in text mode, why bother?
Another thing I just don't get about EasyC is that the "block & C programming" view, and the "C programming view". What's the point? You can't edit anything, all you can do is add a comment?
The only reason to be in any of these viewing modes is to burn up screen real estate.
