@Nick:
Thanks for the explanation, it's very kind of you!
@John:
You are right, this actually works. However, this will also exclude the
trees
whose property value is empty, for example, the following tree will be
excluded,
which will not be excluded if "myproperty<>nil" syntax works:
* Tree
:P

Understood - I like
Try this instead:
#+BEGIN_SRC emacs-lisp
(org-map-entries (lambda () (org-heading-components)) "myproperty<>\"\"")
#+END_SRC
Empty properties get returned as "" not nil I think.

One more question: how do I map only the entries that has a specific
property
defined? The following code didn't work.
(org-map-entries
(lambda () (...))
"mytag+myproperty<>nil")

Thank you very much Nick.
(info "(org) Using the mapping API") was the first doc I read which has
very little information on how to use the "match" parameter. (info "(org)
Matching tags and properties") does have a lot more detail though.
