[NavaTux]

I have written a code 1.erl which i wanna to be connected with 2.erl
to make the link for print some information

1.erl

-module(1).
-Author("nava").
-export([start/0,loop/1]).
start() ->

      Pid = spawn(fun()->loop() end),
      register(nava,Pid).



loop()->
	receive

       		message->
			io:format("This is ur message Nava:~n",[]),
			2:start();                   //to execute 2.erl

		_->
			io:format("Empty"),
			void

		end.



2.erl


-module(2).
-export([start/0,print/1]).

start()->

	Pid1=spawn(fun() -> print() end).

print()->

      receive

           welcome->

		io:format("Success:~n");

		_->

		io:format("try once again u ll get success~n");
	end.
