lets parse it.

Code:

$w2kwxp = @PRODUCTTYPE = "Windows 2000 Professional" OR @PRODUCTTYPE = "Windows XP Professional"

comes to:
Code:

$w2kwxp = (@PRODUCTTYPE = "Windows 2000 Professional") OR (@PRODUCTTYPE = "Windows XP Professional")


and becomes any of these:
Code:

$w2kwxp = (1 OR 0)
$w2kwxp = (0 OR 1)
$w2kwxp = (0 OR 0)


so, afaik, it's "correct" syntax
