in thread Addional "year" matching functionality in word matching script

See perlre for explanation.

\b matches "word boundaries", but in a special meaning of "word". /i makes the matching case insensitive, and /g makes it global, i.e. it matches as many times as it can, and returns all the matching substrings.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

    Ok, i'm near the end of the script now. In this bit, I can see why the script prints out the line from $csv2, but I can't understand how it prints out the line from csv1. I can't see where it gets this information.
    if ($count >= $desired) { print "$csv2\n"; ++$matched; } } print "$_\n\n" if $matched;
    I can see the:
    print "$_\n\n" if $matched;
    bit somehow contains the information from csv1, but I can't see anything in the script which suggests why this would be?
      That's because
      while (<CSV1>) {

      in fact means

      while (defined( $_ = <CSV1> )) {
      ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
