Update: I need to take a closer look at your code.

Could you explain, a bit more abstractly, what it is you are attempting to do? You want the lines which have ' 0.00' at column 118, correct?

First, your bracing and indenting style leaves something to be desired. Here's how I'd write your code:

while (<TEST>) {
  if (/NAME /../ADJ TO TOTALS:/) {
    push @data, $_;

    foreach my $data (@data) {
      if ($data =~ /1235114182/) {
        $lines .= $_;
        my $zero = substr $lines, 118, 5;  # <-- 5? or 4?
        # you had '==', you want 'eq'
        if ($zero eq "0.00") { print OUTPUT "@data \n"; }

        @data = ();
        $zero = $lines = "";
      }
    }
  }
}

You were using == which is for strictly numeric data, but you want to use eq because you're looking specifically for the characters '0.00'. You either want to change your substr() to 4 characters, or else look for ' 0.00', I think.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
