in thread compare text files

Hey, no worries. The code does work fine on my computer; however push(@array,$item); "pushes" a flat variable onto the end of the list. So its just adding it to the list. At the end of the program outside of all loops yes I used:

say foreach @results;

say "hello world"; is like System.out.println() in java, it prints the output with a newline. So when I type foreach @results it just prints out each result with a newline on the end.

Now, in order to use some keywords in perl you must tell it you are using a specific version first, I use v5.14; at the top and you can use say after... 5.10 I think. But you can also write the printout like so if you wanted to print to a results file!:

use v5.14; open(RESULTS,'>','results.txt') or die $!; foreach(@results){ print RESULTS "$_\n"; } close(RESULTS);

The printing should only come after all the computing.. it should not be in any loops. All results should save to the array first and then you can use it at the end. Dont hessitate with any more questions :) good luck.
