in thread Array element removal

Assuming that the critical value has to be in the second position in the array, and if you don't mind building up a new array to replace the old one: 
  my @new_data;
  for my $i ( 0 .. $#data ) {
    $data[$i][1] != $compare[$i] and push @new_data;
  }

  # replace:
  @data = @new_data;

As an aside, you are using global variables unnecessarily. Your code will be a lot clearer and cleaner, and less error prone, if you use lexical variables properly. use warnings; and use strict; to let perl help you write better code.

    I assume that he doesn't want the second elements in the arrays referenced in @data to be contained anywhere in @compare. Your code only checks elements in @data and @compare with the same index. The question wasn't very well stated though.

      If your interpretation is the question that was asked, even with the insight of your interpretation, I can't derive the filter to extract that signal from the noise.
