Comments:

By default, IDXFORMATs 17-21 are unavailable under Enterprise Server. You must ensure the ACUFH and ESACUFH configuration options are both set to ON to use these formats.

You can set IDXFORMATs 17-21 under all tags in the configuration file except the [XFH-DEFAULT] tag.

In cases where the INTEROP and IDXFORMAT settings conflict, the INTEROP setting will override IDXFORMAT.

If you are running your program under an Enterprise Server region, IDXFORMATs 17-21 are not supported.

If you are using Fileshare, IDXFORMATs 17 and 21 do not provide transaction processing capabilities.

Rebuild will not take the setting of this configuration option into account when generating a new file. Refer to the Rebuild Options /t topic in the Reference section for further information.

You can also set the index format using the IDXFORMAT Compiler directive, which will override the setting specified in the file handler configuration file.
