Hi,

Take a look at perlop, here you'll get explained the ternary operator and a indication for what is goind wrong here.

The code really says this:

( (exists $hash{$_} and $hash{$_} eq 'on') ? $result = 'OK' : $result 
+) = 'KO';

And the result of the ternary operator is an assignable value so that it gets to:

$result = 'KO'

With this, it works well

   (exists $hash{$_} and $hash{$_} eq 'on')
      ? ($result = 'OK')
      : ($result = 'KO');

Regards,

Update:
Losed too much time to answer, so it was already answered... next time ;-)

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
