Check out the ALTER TABLE command. This is actually much easier than creating a new table and appending from the original.

>Back in the old FoxPro 2.6 times, I had a program which was able to add fields to any existing DBF; if the structure of the DBF wasn´t what the program wanted, it created a new file, appended everything from the old DBF, added indexes to the new file, deleted the old one, and renamed the new one (whew!).

The standard GENDBC program is great for creating a DBC and its DBFs for the first time, but it doesn´t work when they already exist.
