    Do you mean you want a condition that has to be met ONCE and then is "sticky"? Like: 
    my $keep_going = 0;
while (my $job_B = readdir DIR_B) {
  print "D\n";

  # ||= here means "assign to $keep_going if $keep_going is false"
  $keep_going ||= $job_B =~ /Out_$tag\.txt$/;
  next unless $keep_going;

  ...
}

 $tag= "al";
 opendir (DIR_B, "..");
 $c= 0;
 {TEMP:
 while(my $job_B=readdir(DIR_B)){ 
     print "D $c\n";
     
     next unless $job_B =~ /Out_$tag\.txt$/;
       }
 }
print "DONE\n";
close (DIR_B);opendir (DIR_B, "..");
  goto ("TEMP");

    this will scan the directory. once it finishes reading itll close the file handle for a new one or the same or whatever. You need to be more specific but this might be the goto you were looking for
