work on.  The \fIdata\fR field is given to the remote application.
Typically, the application treats the \fIdata\fR field as a script, and the
script is run in the application.  The \fB\-async\fR option requests
asynchronous invocation.  The command returns an error message if the
script did not run, unless the \fB\-async\fR flag was used, in which case
the command returns immediately with no error.
.VS 8.6
The \fB\-binary\fR option treats \fIdata\fR as binary data, otherwise an utf-8
string is sent.  Combining \fB-binary\fR with the result of


\fBencoding convertto\fR may be used to send data in arbitrary encodings.
.VE 8.6

\fBdde poke\fR ?\fB\-binary\fR? \fIservice topic item data\fR
.
\fBdde poke\fR passes the \fIdata\fR to the server indicated by
\fIservice\fR using the \fItopic\fR and \fIitem\fR specified.  Typically,
\fIservice\fR is the name of an application.  \fItopic\fR is application
specific but can be a command to the server or the name of a file to work
on.  The \fIitem\fR is also application specific and is often not used, but
it must always be non-null.  The \fIdata\fR field is given to the remote
application.

Microsoft Word. \fIservice\fR is typically the name of an application,

.VS 8.6
Without the \fB\-binary\fR option all data will be sent in unicode. For
dde clients which don't implement the CF_UNICODE clipboard format, this
will automatically be translated to the system encoding. You can use 
the \fB\-binary\fR option in combination with the result of
\fBencoding convertto\fR to send data in any other encoding.
