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

It's not too difficult to whip up a routine to do this. VFP provides a number of functions to extract information about the database. You can use aDbObjects to get a list of tables, views, or relations. DbGetProp can then be used to extract information about these objects. For indexes you can use Tag(), SYS(14), Primary() and Candidate() functions to extract the information.
