+If you prefix a command with @samp{server } then it will not affect
+the command history, nor will it affect @value{GDBN}'s notion of which
+command to repeat if @key{RET} is pressed on a line by itself.  This

+The server prefix does not affect the recording of values into the value

+use the @code{output} command instead of the @code{print} command.
