Commands within DFSMShsm are classified as authorized and nonauthorized.

Authorized commands can be issued only by a user specifically authorized by a storage administrator. Generally, authorized commands can affect data sets not owned by the person issuing the command and should, therefore, be limited to only those whom you want to have that level of control.

Nonauthorized commands can be issued by any user, but they generally affect only those data sets for which the user has appropriate security access. Nonauthorized commands are usually issued by system users who want to manage their own data sets with DFSMShsm user commands.
