username-and-rights-list-identifier-list

   Specify a list of usernames and/or rights-list identifiers whose
   holders may watch your terminal.

   Full * and % wildcards are supported for usernames, and the
   UIC:[ggg,mmm] syntax is also supported. It allows a * wildcard for
   the group or member portion of the UIC. Due to the embedded comma,
   the "UIC:[ggg,mmm]" syntax in a command must be enclosed in quotes.

   Each individual item in the list may be preceeded by a minus to
   reverse the sense of that one item so it disallows instead of allows.

   Rights-list identifiers held by a process are displayed by the DCL
   $ SHOW PROCESS/PRIVILEGE command. Once you issue a PEEK/ALLOW command
   specifying an identifier, any users who has been granted that
   identifier may watch your terminal.

   Example:  $ PEEK/ALLOW J_JONES,HELPERS,P_SMITH

   This command allows your terminal to be watched by users J_JONES and
   P_SMITH and all users with the rights-list identifier HELPERS.

   The list is checked from left to right, so

             $ PEEK/ALLOW -J_JONES,*

   would disallow J_JONES but allow anyone else to watch.
