Dear 2Teez,

I've been trying to solve my little programming problem using the module, however, due to my lack of experience, I somehow have not been able to run the comparison properly

What I did not understand in the CPAN description was the fact that only one array is used for the comparison, e.g.

I would have expected to have two @arrays for comparision, e.g.

my @xml_files = glob( '*xml' );
#say for @xml_files;

my @bak_files = glob( '*bak' );
#say for @bak_files;

#using the Text::Diff::Table for comparison

my $format = "";

my @joint_files = @xml_files, @bak_files;

my @results = diff \@joint_files, $format { STYLE => "Table" };

say for @results;

However, I am getting the following error message, saying that the module is not install properly

C:\dev>perl comparing_files_3_using_text_diff.pl ./file_compare_on_lis
+ts

I suppose I have to use the module as is, but what does $b represent and why can't it be changed to $format?

Could somebody give me a hint why I am getting the error message despite the module being installed?

I am confused about these package name declaration, I thought I did everything by the book

Thanks a mil in advance for your support

Kind regards
