Hi Monks,I know its something which I should not ask,but I tried a lot.So now I come to you people to help me out of this

I have written one Perl script to open ping process take its output , parse it and show its output

open CMD, "/bin/ping -c $count -i $interval -s $packetsize -w $allowab
+leTime $host |" or die "Can't open ping: $!";
 while (<CMD>) {
my (@values1,@val1,@values2,@val2,$val) = 0; 
    if ( $_ =~ /PING/ ){
         @values1 = split ;
    
            @val1 = split(/\(/,$values1[3]);
           $val1[1] =~ s/\)//;
             
      }  
    print "$values1[1] \n";
    print "$val1[0] \n";
}

I want to print the last two prints outside if blocks but I am getting warning,I know its related to lexical variable ,but I couldn't figure it out.Warning is something like this :

Use of uninitialized value $val in concatenation (.) or string at ./pi
+ng_linux.pl line 69, <CMD> line 2.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
