<dd>The user can perform all operations on the object except those limited to the owner or controlled by object existence (*OBJEXIST) and object management (*OBJMGT) authorities. The user can change and perform basic functions on the object. *CHANGE authority provides object operational (*OBJOPR) authority and all data authority. If the object is an authorization list, the user cannot add, change, or remove users.
</dd>
</dl>
<dl>
<dt><b>*ALL</b></dt>
<dd>The user can perform all operations except those limited to the owner or controlled by authorization list management (*AUTLMGT) authority.

</dd>
</dl>
<dl>
<dt><b>*USE</b></dt>
<dd>The user can perform basic operations on the object, such as running a program or reading a file. The user cannot change the object. Use (*USE) authority provides object operational (*OBJOPR), read (*READ), and execute (*EXECUTE) authorities.

<dt><b>*LIBCRTAUT</b></dt>
<dd>The system determines the authority for the object by using the value specified for the <b>Create authority (CRTAUT)</b> parameter on the Create Library (CRTLIB) command for the library containing the object to be created. If the value specified for the CRTAUT parameter is changed, the new value will not affect any existing objects.
</dd>
</dl>
<dl>
<dt><b><i>name</i></b></dt>
<dd>Specify the name of an authorization list to be used for authority to the object. Users included in the authorization list are granted authority to the object as specified in the list. The authorization list must exist when the object is created.
