Filter creation exit

The filter creation exit is started when you attempt to create a z/OS® UNIX file filter through the New z/OS UNIX File Filter Wizard or the New z/OS UNIX Subproject Wizard.

Tip: If you attempt to create both a subproject and a filter at the same time, and either the subproject or filter creation exit fails, neither the subproject or the filter is created.

When you attempt to create a z/OS UNIX file filter, the name that you assign to that filter is passed to the external program as a parameter. Messages are displayed in the Remote Console view to indicate which external program was run and if it succeeded or failed. A successful return code of 0 allows the new z/OS UNIX file filter to be created. If the user-specified external program cannot be located, a message that indicates the reason for the failure is displayed in the Remote Console view and the z/OS UNIX file filter is not created.

When the filter creation user exit runs, the exit might contain code that writes data to standard out. This output is displayed in the Remote Console view, regardless of the user exit return code.

You can set the filter creation exit in the User Variables, Exits and Listeners preference page.
