Description

The PACK DATABASE command packs all the tables in the active database. Packing a table removes all records previously marked for deletion from the table.

Databases in Recital are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directories are sub-directories of the Recital data directory. The environment variable / symbol DB_DATADIR points to the current Recital data directory and can be queried using the GETENV() function. Files from other directories can be added to the database using the ADD TABLE command or via the database catalog and SET AUTOCATALOG functionality. Databases are opened using the OPEN DATABASE command.

If the <database name> is specified, the PACK DATABASE command will operate on the specified database's catalog file: the catalog file will be packed and its index tags rebuilt using INDEX ON. If the question mark, '?', is included instead of the <database name>, the 'SELECT A FILE' dialog will be displayed, allowing the user to select the database. The dialog defaults to the DB_DATADIR directory.
