File

Set the default mnemonic for WRITE commands to a sequential file.

Synopsis

[IO]    File=n

n is an InterSystems IRIS® data platform routine name. The default is ^%X364.

Description

The File setting specifies the default mnemonic for sequential files. When an OPEN or USE command includes no mnemonic space argument, InterSystems IRIS uses the default mnemonic for that device type. For more information, see the “Controlling Devices with Mnemonic Spaces” chapter in I/O Device Guide.

Changing This Parameter

On the IO Settings page of the Management Portal (System Administration > Configuration > Device Settings > IO Settings), in the File row, enter an InterSystems IRIS routine name.

Instead of using the Management Portal, you can change File in the Config.IO class (as described in the class reference) or by editing the CPF in a text editor (as described in the Editing the Active CPF section of the “Introduction to the Configuration Parameter File” chapter in this book).
