Try something like this and save the output in 3 files: 
use strict;

my (@year, @name, @asterisk);
while(<DATA>)
{
    chomp;
    my $line = $_;
    while ($line =~ m/%(\d\d\d\d)/g)
    {
        push @year, $1;
    }
    
    while ($line =~m/\$([A-Z]+)/g)
    {
        push @name, $1;
    }
    
    while ($line =~m/\*([^000]+)/g)
    {
        push @asterisk, $1;
    }
    

}

print join("\n", @year);
print "\n";
print join("\n", @name);
print "\n";
print join("\n", @asterisk);
print "\n";
