Use the DISCONNECT command to write any modifications of the currently open database to disk, then close the database.
About the DISCONNECT Command
Use the DISCONNECT command before copying database files, or when you want to leave the open database without opening another database. If you keep your database on a floppy disk, use DISCONNECT to close the database before you remove the floppy disk.
The CONNECT and EXIT commands also close an open database.
If transaction processing is on when you execute DISCONNECT, R:BASE COMMITs (saves) any open transactions.
Example
The following command closes an open database:
