You're example using eval is excellent. I attempted something similar earlier, but my recursive call wasn't correct, but looking at your example, I understand why.
The other part of this program is to make the program output and arbitrary range of program lines, and trying to duplicate that code via the method I was using earlier was a real pain. Using this method, it should be much easier, although I wish I could execute code that was in an array directly, because it would make my life easier.
UPDATE: I implemented my existing code using this method, and it works very, very well. Thank you again for your help!
