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.

DISPLAY commands differ from LIST commands in that they pause every 17 lines until a key is pressed. You can cancel any further output at this point by pressing the [ABANDON] key. Where the output is sent to a file or printer, the pause is disabled.

Keyword	Description
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. The command SET PAGELENGTH governs the output file pagination and SET PAGEWIDTH defines the width of each page. Page numbers are centered on the bottom of the page according to width.
TO PRINT	The display output will be sent to a printer. The TO PRINT option will default to a local printer unless the command SET PRINTER TO \\SPOOLER is issued. The print request will then be spooled to the system printer, which is defined by the environment variable DB_PRINT.
