/regexp/ monks,

I have the following 

__DATA__
blah blah blah

blah blah blah
blah blah blah
          blah blah blah

INTERESTING CODE--
  CODE     NAME                    CODE     NAME                      
  -------- ----------------------- -------- -----------------------
  ABC      NAME ONE                RST      NAME EIGHT ...   
  DEF      NAME TWO THREE          WXY      NAME NINE - TEN
  GHIJK    NAME FOUR ...           ZAB      NAME ELEVEN
  LMN      NAME FIVE - SIX         CDE      NAME TWELVE
  OPQ      NAME SEVEN 

more blah
blah blah

I want the following 

#########################
print $interesting_code;

# output
"NAME ONE, NAME TWO THREE, NAME FOUR ..., NAME FIVE - SIX, NAME SEVEN,
+ NAME EIGHT ..., NAME NINE - TEN, NAME ELEVEN, NAME TWELVE"
# you get the picture... a csv list of NAMEs
#########################

I have almost solved the above, but my code is so juvenile that I put it forth here with great embarassment. It is also not producing the correct output, and is certainly not going to hold for variations in the above. While there could be variations in the INTERESTING CODE block, it would still be formatted as above. A two-column set of two columns, the CODE followed by the NAME 

my $stuff;
my @stuff;
while (<DATA>) {
  if ($stuff) {
    push(@stuff, $_) 
      if (!($_ =~ /^\s*CODE\s*NAME/) && !($_ =~ /^\s*-+/));
  } else {
    $stuff = 1 if ($_ =~ /^INTERESTING CODE-+/);
  }
}
my @interesting_code;
for (@stuff) {
  my @code = split(/\s{2,}/, $_);
  my $i = 0;
  for (@code) {
    push(@interesting_code, $_) if !($i % 2);
    $i++;
  }
}
$interesting_code = join(', ', @interesting_code);

I seek edification; and better, and more dependable code. All advice welcomed with gratitude.

Update: Reformatted so one wouldn't get a headache from reading it.
