Hello, Look at the below code, it returns an array from a sub.

@array = ("hi","hello");

@final_array = match_files(\@array);


sub match_files
{
        push(@files, "hola", @array);
        return @files;
}


for (@final_array)
{
        print;
}

Your problem is you are storing the results of the sub which are an array into a scalar varialble.
