Tcl-DP: Id Server

This example creates a simple Id server, where an Id is an
integer.  Two very short Tcl/Tk scripts are supplied:

   idServer.tcl -- the Tcl/Tk script for the server
   idClient.tcl -- the Tcl/Tk script for the client

Please read them and edit them as they suggest.

--------------------------------------------------------------------

To run the idServer...

Run dpwish.
Type "source idServer.tcl".

--------------------------------------------------------------------

To run the idClient...

Run dpwish, as another process.
Type "source idClient.tcl".

--------------------------------------------------------------------

From the idClient dpwish, type your own RPC commands to experiement
with the system.  Remember, the arguments you give to the RPC command
are evaluated in the idServer's interpreter, and the result of
that remote evaluation is returned.  For example, in the idClient
dpwish, you can type:

RPC $server expr 1+2
RPC $server set x 100
expr $x
RPC $server eval {expr $x+$x}
RPC $server puts stdout hello

To get more id's, type:

RPC $server GetId

--------------------------------------------------------------------

Try running more than one idClient.
