A simple condition?

How do I determine whether among all instances there exists an instance with key set to specific value? It has to be a condition. Like this:

NEGATIVE (Exists? Hashtable("Key")="Test")[/code:2ckfbmej]
I would like a clean and simple solution rather than having to devise a bulky workaround.

for each "my object"

+"my object" private variable "key" = "yes"

do actions

That is what I was not looking for, I was hoping for a system expression or an evaluation that checks if ANY object instance has a certain key with exact value, but oh well, I'll have to go with a workaround, which requires a whole event and is rather unwieldy.

Hmm, come to think of it, I'll need some sort of 'search' function after all... that searches all hashtables for an exact key and/or value. Might as well create a function especially for that.

Thanks, though!
