The Pathname field displays the path name of the selected file. The Type field display the file type for the selected file.

The owner of the file can be changed by a superuser by updating one of these input fields on the panel:

UID Number: This field allows you to enter the UID of the new owner. This must be a number, in the range 1 to 2147483647, and must be defined as a z/OS UNIX UID in your security data base.
User ID: This field allows you to enter the user ID of the new owner. The user ID must be defined in your security data base and have the authority to use z/OS UNIX resources.
