OD>Huh? What is ADX? It is the 32bit version of DX, as EAX is of AX?

So, I can use ADX like any other register, then?

Funky.  Funky how a three-character mnemonic can signify that much over 
another of no less characters.. :)

Quick-Basic also runs off a command-line compiler...  And Quick-Basic's IDE 
simply RULES!  Give me ONE other IDE that actually CORRECTS you in real-time, 
and checks syntax like that?
What does you IDE do that the others don't?

Hey, talking about real-time interpreters... I know some BASICs relied on a 
BASIC chipset.. Do they still make processors with those chipsets?  Or 
compilers that actually use them?
See ya around!
