sysitems

Arguments: dde-info

Returns the value of the sysitems property of the Lisp DDE server process associated with dde-info, which must be an instance of dde-info.

If another program opens a client DDE port with the "System" topic and connects to a DDE server running in a Lisp process, and then it issues a DDE request for the "sysitems" item, then a built-in answer-request method will return the sysitems of the Lisp server process to which it connected.

The value should be a list of item names to which the Lisp DDE server will respond if the items are sent in requests using the "system" topic. The sysitems for any Lisp process will initially be the value of the variable *sysitems*, but you may call (setf sysitems) at any time to change the sysitems for a particular process.

Call dde-info to retrieve the dde-info instance of a particular Lisp process.

See dde.htm for information about DDE support.
