The formatting in your post is mucked up somehow. There are real <code> tags in there (perhaps because you're not closing your <code> tag?), which means spacing isn't preserved. So everyone can see what you're talking about:

Name            ID      PS      Gender     Age      Month    Code     
+ Cap        Pool
LName, FName    99999   99        M        99.9     12/2000  Add      
+ 99.99      99.99
                                                    11/2000  New      
+ 99.99      99.99

I almost think what you want is a flexible regular expression, but if this is a fixed-length string, perhaps unpack will work for you.

$_ = "LName, FName    99999   99        M        99.9     12/2000  Add
+       99.99      99.99";

my @keys = qw{ name id ps gender age month code cap pool };
my %info;

@info{@keys} = unpack("a16a8a10a9a9a9a10a11a8", $_);

foreach (@keys) {
        $info{$_} =~ s/\s*$//;
        print "$_='$info{$_}'\n";
}

Adjust the unpack format to match your string (the number of characters per field seems to jump all over the place, but this is probably because it was typed and not cut/pasted), and you should be in good shape.
