*sysitems*

The value of this variable is the default value for the sysitems property of any Lisp DDE server created by calling open-server. The initial value is the list of symbols (:sysitems :topics :help), but you may modify the value of this variable to use a different default set of sysitems.

The initial value follows a DDE convention where a "sysitems" item may be passed along with the "System" topic to a DDE server to find out what other items are available on the standard "system" topic.

While any Lisp DDE server will initially have the value of *sysitems* as its sysitems property, (setf sysitems) may be called after calling open-server in order to customize the system items of the DDE server running in a particular process.
