The Server Prefix
*****************

   To issue a command to GDB without affecting certain aspects of the
state which is seen by users, prefix it with `server '.  This means that
this command will not affect the command history, nor will it affect
GDB's notion of which command to repeat if <RET> is pressed on a line
by itself.

   The server prefix does not affect the recording of values into the
value history; to print a value without recording it into the value
history, use the `output' command instead of the `print' command.
