Greetings oh wise ones. I'm working on a simple client/server script that just talks back and forth, but I'm having trouble with the script not processing my if statements after data is sent to it. I will then however continue on after more data is sent and stop again at the same place. The ####Problem here.#### is where the server stops after I send it the first bit of information. Here is the code minus some of the basic socket stuff which I omitted.

Server 
while(1){
    $MySocket->recv($text,2);
    if($text ne '')
    {
        print "\n Number'", $text,"'\n","\n";            
        ####Problem here.####
                if($text=~m/\d.*/){
            print "\nThat's a number";
        }else{
            print "\nNot a number";
        }
    }else{    
            print "Cilent has exited!";
                exit 1;
    }
}

Client 
print "\n",$def_msg;
while($msg=<STDIN>)
{
    chomp $msg;
    if($msg ne '')
    {
        #print "\nSending message '",$msg,"'";
        if($MySocket->send($msg)){
            print ".....<done>","\n";
            print $def_msg;
        }
    }
    else
    {
        # Send an empty message to server and exit
        $MySocket->send('');
        exit 1;
    }
}

After the server reads in the input it runs the print statement with the:

print "\n Number'", $text,"'\n","\n";

But it won't run the if statement after it until I sent another piece of data from the client E.G. I fire open the client and type in the number 1 then hit enter. My server prints this output: 

>> Server Program <<

 Number'1'

And stops there until I enter something else on my client; say I enter the number 2. My server now looks like this: 

>> Server Program <<

 Number'1'

That's a number
 Number'2'

So it moved on to the if statement only after seeing more input from the client. Any ideas?
