Mayayana,

Because its a two-in-one step: if the result is not-empty I use it, if not I 
know I need to do something in relation with the key, store the result and 
use it.  In short, a cache.

But thats something else thats rather odd: The dictionary doesn't throw an 
error when the key doesn't exist. Instead it returns a null.   I know that 
it does away with having to use "exists" beforehand, but whats the logic in 
that ?

In short, what where the people thinking when they purposely wrote the 
method that way ?

:-) How than do you know whats (already) in there ?    Normally I do not 
exactly know what the file contains my code is trawling thru, and certainly 
will not gamble on those contents being perfect.

Static arrays are very costly when you want to add a record.   Mind you, 
I've used VBScript on a 256 MByte (yes, Mega) Win98 machine.    It payed off 
to be a bit carefull with what you did memore wise.
