Does the "@" symbol act as a pointer in header files for Registers?

I'm using CodeWarrior 10.6.4 for an MC9S08QB8 device.  I'm fairly new to using the C-Language with micros, but I'm getting there.

A question has arisen from a colleague of mine who has used C much longer than me.  In particular, I reference Page 40 of the "Getting Started with HCS08 and CodeWarrior Using C, Rev. 2" document.  On that page there is a reference to using the "@" symbol as an "absolute address" to location $0065.  In trying to help me with my own understanding of how registers are accessed, he doesn't understand how the "@" symbol is used in the typical device headers (as indicated on Page 40).  He has tried to implement the "@" symbol in his own C-Development environment for one of his own projects (not CodeWarrior), but it was not acceptable there.

How does CodeWarrior/Eclipse treat the "@" symbol?  What is it's meaning?  Is it related to pointers?
