Description
The DISPLAY INDEXES command is used to display index information about the currently active table. Information is displayed for both production and single index files.
The DISPLAY INDEXES command displays the following information:
- Production DBX file name
and for each tag:
- Tag name
- Key
- Type
- Length
and for each open single index:
- Index file name
- Key
- Index cache size
The master index tag is flagged as such.
TO <file>
The display output will be sent to the specified file. The filename can be substituted with a <expC>, enclosed in round brackets, which returns a valid filename. If no file extension is specified, then ".txt" will be used.
Example
