 \fBdde request\fR is typically used to get the value of something; the
 value of a cell in Microsoft Excel or the text of a selection in
 Microsoft Word. \fIservice\fR is typically the name of an application,
 \fItopic\fR is typically the name of the file, and \fIitem\fR is
 application-specific. The command returns the value of \fIitem\fR as
 defined in the application.  Normally this is interpreted to be a
