>I would like to convert this file type, or creat a programme to convert this file type for use with VFP5. There is Long, Boolen and Double filed types in the file. Any help would be appreciated

You have several options here, none of them particularly attractive if what you want to do is handle as if it were a .DBF or database accessed via an ODBC driver. You can probably process the file using low-level file I/O, and convert the structures to native VFP datatypes by parsing the record and converting the binary data as written to VFP memory variables one record at a time.

Another alternative would be to create a COM Object in VB, and have VB handle the I/O and parsing for you. You would then have VFP instantiate the VB COM Object, and talk to it through an OLE interface. This would simplify the conversion process; The VB server would read and parse the data, and VFP would then pull data members from a collection. This would probably be the easiest to implement if you needed to read and write the file, since undoubtedly there's existing code in VB to do basic file handling.
