The source code in this archive works with Think C 5.04. I still haven't updgraded to the latest version of the compiler, because I find that 5.04 is reliable and fast and works in a relatively small amount of memory. Version 8.0 is available and it's only a matter of time when I will have to move onto the new version. Universal headers will probably require some changes, but it should all be pretty easy.

Good luck,
