Ok. Let me see if I got this right - you're complaining that if you enter 7 at home, it will print 6, but that if you enter 7 at work, it will print 7 ... ?

First off, the indices of an array go from 0 to $#lines. So, when you do $number1 <= 0 as a boundary condition, you're already cutting off one of your useable indices.

The second thing is that you're comparing the number they give you (from 1 .. N) to a range from (0 .. N-1). I would do a $number1--; right after the chomp.

The third thing is that you're using | (the bit-wise OR) when I think you mean to be using || (the logical OR).

A few style notes:

• if (!$blah) should be written unless ($blah)
• Never use a variable named $number1. Instead, use something like $link_num.
• I'd change your file-reading to something like this. It's clearer exactly what you're trying to do, which is to take in all the lines, then reject a certain type of line.

  open IN, "<$filename" or die "Cannot open $filename\n";
  my @lines = <IN>;
  close IN or die "Cannot close $filename\n";
  @lines = grep !/\s*[a-qs-zA-Z]/, @lines;

• The \s* in your regular expression is useless, in that it doesn't add any restrictiveness. Generally, you don't see \s* in matches, just substitutions.

Hope this helps!
