Description
The DISPLAY FILES command displays filenames in the current directory and path (see SET PATH) matching the specified <skeleton>. The following 'wild card' characters may be used
| Character | Description |
|---|---|
| ? | Matches any one character. |
| % | Matches any one character. |
| * | Matches zero or more characters. |
If DISPLAY FILES is issued with no <skeleton> specified, then it will list details of table files only.
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. |
