>I would like to generate complete documentation od tables, indexes, connections among tables, relationships... from DBC file (V6.0)

Look at the VFP Documenting Wizard for native tools. If you have Visual Studio, Visual Modeler is a part of the Visual Studio product.

There are several common 3rd party add-ons used with VFP that have good documentation capabilities - two of the ones I've seen used fairly often are XCase and SDT. Neither is free. Both are good VFP tools - I use SDT in my own products, and know other people who use XCase and like it a lot.

A number of third party tools are designed to handlke reverse engineering and documentation of VFP (and other products) databases; some examples include Rational Rose, Viso Professional (there are Visio add-ons that extend Visio's nativie capabilities like 4Keeps), ERWin and EasyER are a few of the common tools. Again, they are not free, and are not a part of VFP itself - in fact, many of the tools mentioned access the VFP DBC via ODBC connections.
