OpenMode

Specify read/write mode to use when opening sequential files.

Synopsis

[Miscellaneous]    OpenMode=n

n is either 1 (true) or 0 (false). The default value is 0.

Description

OpenMode specifies the default read/write mode to use when opening sequential files with the OPEN command. The options are Read-Write (1) or Read (0).

Changing This Parameter

On the Compatibility page of the Management Portal (System Administration > Configuration > Additional Settings > Compatibility), in the OpenMode row, click Edit. Choose a mode, Read (0) or Read-Write (1).

Instead of using the Management Portal, you can change OpenMode in the Config.Miscellanous 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).

To change this parameter for a single process only (as opposed to instance-wide), use the OpenMode() method of the %SYSTEM.Process class. See the class reference for details.
