Which version of JScript?

iHD uses ECMA script (compact profile)
ECMAScript is often referred to as JScript or JavaScript, although technically these two languages are both extensions of the ECMA-262 standard. HD DVD uses its own subset of the ECMAScript 3rd Edition Compact Profile (ES-CP). Reference:MSDN

262 is ECMAScript Edition 3

327 is the Compact Profile, which basically restricts the use of with, eval, and the Function constructor

iHD uses 327 with the additional constraints that:

* You must use semicolons (ie, no automatic semicolon insertion)

* The "optional" parts in the Annex of 262 (like octal literals and string.substr) are not implemeneted
