No Field_GetString(), Cursor_NextRecord().

I don't know if SetMedia() is used, but I am sure to exclude database
corruption problem and my C code work correctly on new db (VarChar
included).

I use Christian Bauer's MAC emulator in order to dump data by VAPP.
Unfortunately I get crash after 10Mb of ASCII output (400Mb left). It's
possible a emulator failure. :-( However, I import this file into
clone/remake db, then everything is going smoothly, excellent.

About Valentina Studio for Windows tests, it reads database structure only,
crash on attempt to browse data, unlike VAPP. Dump just as before, 3 record,
20Kb. Diagnose explain...

I apologize for being slow to reply. I give up a lot of time to Valentina
applications.
