Hello Hash Honchos,

I have a subroutine which returns a hash, except when things go wrong, in which case it returns undef. I then want to test the result to see what happened:

my %hash = getHash();

if (%hash == undef) {
  print "undef\n";
} else {
  print "not undef\n";
}

Those of you in the know will see that this does not do what I expect. Can anyone enlighten me as to what is going on?

Thanks

loris
