Im not sure why its not searching in the sub dir. Im trying to find all files with .sas extension and change the permissions for each .sas files. Thanks in advance for your help. Here is the code: 
&recurse_dir("/cdw/home_dir/s006258/CSPAM");

sub recurse_dir {
   my ($dir) = @_;
   opendir(DIR, "$dir") or die "Unable to open $workdir:$!\n";
   my @names = readdir(DIR) or die "Unable to read $workdir:$!\n";
         foreach my $name (@names) {
            if (-d $name){ 
                print "$name is a dir\n";
                if ($name eq "." || $name eq ".." || $name eq "lost") 
+{
                    next;
                }
                else{ 
                    recurse_dir($name);
                }
            }
            else {
                if (-f $name){ 
                    #print "$name is a file\n";
                    if ($name =~ /\.sas/) {
                        system("chmod 644 $name");
                        print "$name has been changed\n";
                    }
                }
            }
        }
}
