**Notes**

1      The Clarion ODBC file driver supports the listed items, however, the underlying file system may not support all of these items.

2      We recommend using a variable password that is lengthy and contains special characters because this more effectively hides the password value from anyone looking for it. For example, a password like "dd....#$...*&" is much more difficult to "find" than a password like "SALARY."

**To specify a variable instead of the actual password in the Owner Name field of the File Properties dialog, type an exclamation point (!) followed by the variable name. For example: !MyPassword.**

3      International sorting is assumed to be done by the underlying file system. As such the OEM attribute and the .ENV file are ignored.

4      PREVIOUS is not supported in file order.

5      See also //PROP:Logout// in the //Language Reference//.

6      THREADed files do not consume additional file handles for each thread that accesses the file.

7      BUILD(index) sets internal driver flags to guarantee the driver generates the correct ORDER BY clause. The driver does not call the backend server.

8      Whether LOGOUT also LOCKs the table depends on the server's configuration for transaction processing. See your server documentation..
