The UIC (User Identification Code) is a 2-part number or
       text string that identifies a user and determines his or her
       relationship to other users on the system. The UIC determines the
       ownership of files and is assigned by your system manager. UICs
       can be either numeric or alphanumeric:

       o  A numeric UIC consists of an octal group number and an octal
          member number.

          You can use the asterisk (*) wildcard in place of the group
          number to identify all group numbers and in place of the
          member number group to identify all member numbers.

       o  An alphanumeric UIC is a text string consisting of a member
          name and, optionally, a group name.

          You can use the asterisk (*) wildcard in place of the member
          name in an alphanumeric UIC but not in place of the group
          name.

       The UIC is enclosed in square brackets or angle brackets. A comma
       separates the two parts of the UIC. The first part of the UIC
       identifies the group of users a person belongs to. Group members
       share the same first number or group name in their UICs. You can
       control access to files according to UIC group numbers or group
       names. The second part of the UIC identifies the individual user
       in a group.

       In an ACL entry, you can use three types of UIC to identify
       users:

       o  By specifying all the digits of both parts of the UIC, you
          can identify one or more users who log in with the same UIC
          associated with their process. For example:

              UIC = [240,240]

       o  By using an asterisk (_*) as a wildcard in place of the second
          part of the UIC, you can identify users who belong to the same
          group and share the first part of their UICs. For example,
          the following specification can identify users with UICs
          [240,101], [240,300], [240,544], [240,777]:

              UIC = [240,*]

       o  By using asterisks in place of both groups of digits in the
          UIC, you identify all users, regardless of their UICs:

              UIC = [*,*]

          You must include the comma and enclose the UIC specification
          in square brackets or angle brackets. If you specify no
          UIC for an ACL entry, the dictionary supplies [_*,_*] as a
          default.
