Thanks Sven, noted and understood. In practice I've changed them all to 
qwords since this is the native size of the system being emulated, which 
leads to another question. If I have a field and property like

fPB1L: qword;
..
property PB1L: qword read: fPB1L write SetPB1L;

procedure ...SetPB1L(p: qword);
begin
   Assert((p = 0) or (p = 1));
   fPB1L := p
end;

is there an unobtrusive way of changing the property to effectively be

property PB1L: qword read fPB1L write fPB1L;

when assertions aren't being generated? The obvious way would be to use 
lots of  $IFOPT C+  but is there anything more concise and maintainable? 
Can methods be inlined, and could the compiler successfully optimise-out 
a method which was a simple assignment?
