    Yes, the vrbls are of course defined higher-up. btw, I'm starting to 
deliberately use my own 'hoisting' techniques. But maybe that's not 
adviseable.

    I'm just on a 'learning exercise', and thinking of  perhaps obfuscating 
the data (in the internal tables) of my pages. This has nothing to do with 
JS, but, as I said, I'm just trying to get a bit of knowledge about 
obfuscation techniques for later in my development.  I'll be looking around 
(a few months from now) about how to encrypt table data, so that the client 
browser shows the info correctly, but the 'sniffer' of the table data has a 
difficult time de-obfuscating.

Thanks for the response.
