The SHOWOPEN command generates information on open disk files including the owner of the file, the family, and family member information.

When you are trying to use the CLOSE (Close Pack) or RES (Reserve) commands on a disk, you can use the SHOWOPEN command to determine what tasks are using files on the family. When using the RES system command, you can use the <range> specification to determine what tasks are using files in the target area of a RES command. When you are trying to determine what tasks are using a particular file or set of files, you can use the SHOWOPEN file and directory variants to display that information.

Explanation

The SHOWOPEN command generates information about open files. You can use this information, for example, when you are trying to close a pack with the CLOSE (Close Pack) command, but open files prevent the pack from being closed.

The maximum number of users displayed for a single file is approximately 200.
