# idClient -- Tcl/Tk script that connects to and accesses the

# You will have to change the value of the host variable

# You may also have to change the value of the port variable, too.
# Look in idServer to also make sure the port variable values match.

# This remote process, of course, should be the idServer.
#
# dp_MakeRPCClient will return a file handle to represent the RPC
# connection to the idServer.  We'll save this file handle in
# the variable called server.

#
# RPC will send the string "GetId" to the remote process, 
# the idServer, which will eval the received string.  Any return 
# value of that remote evaluation is sent back, which we will print.  
# That's it!
