Description
The LIST TRIGGERS command is used to display to the screen all triggers that are associated with the currently active table. A trigger is used to call a procedure written in the Lianja/4GL. Accessible through the CREATE | MODIFY work surfaces, and through SET commands, triggers may be inserted at table, field, record, form, and report levels.
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. |
