In the SDT Designer I can change the Caption in the Indexes for a table to a meaningful string. If I then go to xcase, make some minor changes, then update the DBC from the xcase model, and then do xcas2dbc.prg, the Captions in all tables change to some unpredictable string. Ths string is always meaningful not random, but I've no idea waht it decides to put in. Sometimes it seems to be a field or table name for the current table, sometimes it seems to be a descriptive string from some other unrealted table.
