I have an input file of the form : 
MML v2.0;
import defaultunit;
unit conversion on;

math top {
    t.min = 0;
    t.max = 3600;
    t.delta = 5;
        .........

I need to extract the t.min and t.max values. The code i have written does not print the value but prints t.min and t.max a 1000 times. 
#!usr/bin/perl

use strict;
use warnings;
use Getopt::Long;

my $file;
GetOptions("f|file=s" => \${file}) or die "invalid option\n";
if ($file)
{
  my $fname = $file;
  open (INFO,"<",$fname) or die " Could not open\n" ;
  open (OUTFO,">>","text.txt") or die "Could not open\n";
  my (@line, $myline); 
  @line=<INFO>;
  foreach $myline(@line)
  {
     if($myline=~ /(t\.min=)(.*)(;)/)
     {print OUTFO "tmin = $2\n";};
     if($myline=~ /(t\.max=)(.*)(;)/)
     {print OUTFO "tmax = $2\n";};
  }
close OUTFO;
close INFO;
}

Please help. Thankyou for all the help. I have to parse the whole file and print to a text file, i have gotten stuck in the first step itself, am kind of worried now. Thanks again.
