Correct.

Incorrect.

A or A() passes the array itself.
A(0) passes the first item (whatever type it is)
A(100) Passes the 101th item (whatever type it is)

IF you're calling a Win32 API function (like CopyMemory) that expects a 
pointer, you can pass VarPtr(a(XX)) (or a(XX) by ref) and they can work 
out the rest from there, but anything that expects or returns "an array" 
needs the full array, unless it also accepts an offset as a separate 
parameter.
