    For tablet:

    That's it. For my test file I just copied the original source text into result.txt.   After running it I saw:
    use strict;
    use warnings;
    use Tie::File;
    
    # tie @array to filename using Tie::File
    tie my @array, 'Tie::File', 'result.txt'
    ||||or die "Cannot open result.txt:$!";
    while( <result.txt> ) {
    ||||for(@array) {
    ||||||||my $pattern = "The text to be searched in differnt lines inclunding whit
    e lines and indentation";
    ||||||||my $replace = " The replacing text also in multiple lines including whit
    e spaces and white lines ";
    ||||||||s/$pattern/$replace/;
    ||||}
    }
    untie @array;
    

    For sunadmn:
    It seemed to just work fine for me, once I realized I hadn't told it which section to print. That is, I'd originally typed just "=head1 burble". It was looking for "=head1 SYNOPSIS" in particular.
