There is a tiny mouse cage. In the cage is a spinning wheel. There is also a lepracan. When you add a record the lepracan temps the mouse with a piece of magic cheese. This causes the mouse to run in the wheel, and VFP counts the wheel rotations. The lepracaun just knows by magic when to give the mouse the cheese... so, you get the next id.

Actually, I believe a few bytes unused in the .dbf header was stolen to store the next id value. If you already have values, when you change the type to auto-increment you can specify the 'next id' so it wont conflict with your existing numbers.
