Folks,

In MI, to access some data you need (in general) a space pointer
to the data. Several objects have addresses to other objects in
them. How does one turn such an address into a pointer?
(without patching the program and making a counterfeit
pointer). Similarly, some associated spaces have useful
data in the *functional part* of their associated spaces 
(e.g. debug information for *MODULES). The SETSPPFP
instruction does not give you access to the functional part.

Are there any new MI-instructions for this that I don't know about?
If not, are there APIs that I don't know about? and how do
these do their magic?
