    Topic complex Table functions
    Function closedb()
    Short Closes a table
    Syntax CLOSEDB(tabellenhandle : INTEGER [;dir : STRING) : INTEGER
    Parameter db : table handle from OPENDB
    Return error code
    0 = successfully closed
    See also:
    opendb() reopendb()
    Description At the end of the programm all tables are closed automatically. Nevertheless opened tables use system ressources like memory and file handles and should be closed as soon as they won't be used anymore.

    Attention: All write operations made to a table are not buffered by the tdbengine. The changes are directly visible for all users after the operation has finished.

    Example 1: OpenDB + ReOpenDB + CloseDB



    VAR db : INTEGER
    IF db:=OpenDB('database/adressen.dat','',0,0) THEN //read access
      ..
      ReOpenDB(db,15) //enable write access
      ..
      CloseDB(db)
    END
