Another code:

use IO::Socket::INET;

use IO::Select;

syswrite(STDOUT,"----- Server Program -----\n");
 

$socket=new IO::Socket::INET->new(LocalPort=>1234,Proto=>'udp') or die
+ "socket() error: $!";

$select=IO::Select->new($socket);

LOOP:

while(1)

{

 if(@readers=$select->can_read(0.1))

 {
  $socket->recv($msg_in,128);

  syswrite(STDOUT,"\nPeer>$msg_in");


  }
 else
 {
  syswrite(STDOUT,"Enter message to send to server : ");

  sysread(STDIN,$msg_out,100);   
   
  send($socket,$msg_out,0,'localhost');
  
  goto LOOP;
 }

}

exit 1;

==============================

use IO::Socket::INET;

use IO::Select;


syswrite(STDOUT,"----- Client Program -----\n");
 

$socket=new IO::Socket::INET->new(PeerPort=>1234,Proto=>'udp',PeerAddr
+=>'localhost') or die "socket() error: $!";

$select=IO::Select->new($socket);



LOOP:

while(1)

{

 if(@readers=$select->can_read(0.1))

 {
  $socket->recv($msg_in,128);

  syswrite(STDOUT,"\nPeer>$msg_in");


  }
 else
 {
  syswrite(STDOUT,"Enter message to send to server : ");

  sysread(STDIN,$msg_out,100);   
   
  $socket->send($msg_out);
  
  goto LOOP;
 }

}

exit 1;

But when i send messages from client the server doesn't print the data on screen but in order to print it i have to change line(newline).It acts like it buffers the data.I would appreciate any ideas.
