  I've never noticed that problem. Why would anyone check
the value of a key without knowing it exists? There is an
Exists method, but even that shouldn't normally be necessary.

  The VB Dictionary is coming from scrrun.dll. I love Dictionaries.
The author of the O'Reilly VB book pointed out that they're much
faster than Collections, which I rarely use. But I stick to VBS for
Dictionary use because the scrrun dependency in VB can be a
problem and it's not designed for native code efficiency. Really,
saying that VB has FileSystemObject and Dictionary is just a
sleight of hand. VB doesn't have those. It's just able to use
scrrun and a lot of people decided to pretend VB and VBS are
the same thing.

  When I want something similar in VB I write classes that store
arrays. But in VBS I find Dictionaries a great way to store loads
of complexly related data.
