It's an undocumented tweak in assembly code that generally provides a 17% speed increase on certain archaic chipsets.

thanks ppl... a lil more details please?? moving between directories in parent directory or?? and what programming language is it? Perl? :Q

Well speaking genererally of programming, that is going to output to "\.. ..\" because the \\ will be interpreted as a single \ because it's being escaped.

not sure what \.. ..\ actually does, but I know I've seen some weird stuff before in my settings of visual studio and the directories that looks something similar to that syntax. maybe I'm thinking of \..\..\..\ which would just mean their are 3 directories between the beginning and end of the path.

I know in HTML you can use .. to move up a directory. So say your webpage is in the http://www.anandtech.com/images/index.html directory, you want to link http://www.anandtech.com/porn/omg.gif. Your img tag would probably look like this <img****** = '../porn/omg.gif'>. Of course you could always use <img****** = 'http://www.anandtech.com/porn/omg.gif'>, but you can't do that with normal programming.

for some reason "<img s r c" isn't working.

Does look a bit like, but not exacly like, directory traversal. You sure you got it right?

Its not necessarily any programming language btw. If you want to move down a directory you would do 'cd ../', or down 2 directories, 'cd ../../'

Wouldn't that be moving up? Or just using different semantics?

Up then, if up is 'backward'...

OP: we really mean 'toward the root directory'.

Yah toward the root. I'm picturing this from a tree structure. But since the top of the tree is the root, moving up the tree would be towards the leaves and moving down the tree would be towards the root. WHICH IS IT!?! 🙂

I doubt the prof is looking for moving up in a directory traversal.
