b Here is a simple program for keeping track of files in a directory. It keeps a list of files and a one line description for each, and compares this list to the actual directory contents when it's run. If a new file has been added, it asks for a one line description. If a file has been deleted, it removes the entry from the list of files. It is written in AVL, but can probably be implemented in C without too much work. Anyone else have other quick but useful programs like this? -Bill Ezell, Software Innovations, Inc.
