Hello Robert,
CRDSUE> I guess that USER32 things are defined & implemented in a DLL with a
CRDSUE> name like USER32, and the WinApi things are defined & implemented in a
CRDSUE> DLL with a name like WinApi (or is it KERNEL32?).

Windows API is implemented in set of DLL such as kernel32.dll, user32.dll etc.
The interface (for C programmers) is defined in set of "header files" such as
winbase.h, winuser.h etc. There are not 1 to 1 correspondence between these sets.

BlackBox has 2 set of modules describing the same API DLLs each in own manner.
In particular the WinApi module contains the interface to the same DLLs as modules
KERNEL32, GDI32, USER32.
"Obsolete" modules are more convenient (IMO) but less comprehensive then "new"
modules, which likely was autogenerated from .h files.

CRDSUE> 1 - Why are there duplicate implementations of thousands of apparently
CRDSUE> identical functions?
There are no duplicate implementations, but duplicate interface.

CRDSUE> 2 - Is it a reasonable generalisation that if a WinApi function is VERY
CRDSUE> similar in name to another (eg USER32) that it will behave the same, or
CRDSUE> is it necessary to scrutinise the small print of the Microsoft
CRDSUE> documentation in every case?
It will behave the same, because it is the same.
CRDSUE> 3 - Why are Oms telling us to switch to WinApi - what is wrong with the
CRDSUE> others?
Having two interfaces seems wasteful and the Win subsystem defines much more
functions then all obsolete modules.
