in reply to do while loops

ok.. the code is bad. That situations cause problems to novices

$value=5 <------ ok that is the problem it does not have ;
do{
  print "$value\n";
  $value=$value-1;
} while($value>10);

ok the correct code is

$value=5; # now have ;
do{
  print "$value\n";
  $value=$value-1;
} while($value>10);

Actually, I think the problem is larger than that.
shouldn't it be:

$value = 15;  # 15, not 5. 5 doesn't make sense if we're not increment
+ing.

do {
    print "$value\n";
    $value = $value - 1;
} while($value > 10);

The point was that the test happens at the end, so the loop executes once even if the value starts out < 10.
