my Perl codes read each line in an array, but how can I join only the two lines of the Description?

============================================
open IN,"In.txt" or die "Can't read  \n";
   my @array=<IN>;
   chomp;
   for my $array (@array){
       $array=~s/^\s*$//;
       my @field=split(/";"/, $array);
       for my $field (@field){
       .....
       }
    }
    close IN;
