Set the default mnemonic for WRITE commands to a sequential file.
n is an InterSystems IRIS® data platform routine name. The default is ^%X364.
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.
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.IOOpens in a new tab class (as described in the class reference) or by editing the CPF in a text editor (as described in Editing the Active CPF).
