> Do these positions are different, depending on microprocessor being used ? I'm fairly certain that is an error in the documentation, and that it SHOULD always be as you discovered it to actually be. As an aside, a tip for doing pointer arithmetic... var s : ansistring; p : ptruint; p := pointer(s); dec(p); // equivalent to p:=p-4 because p is a typed pointer. Using typed pointers in this way will likely make it easier to adapt your code to a 64-bit conversion in the future. Also note that, in this case, dec(p,2) would do p:=p-8, as (hopefully) expected I use these types of constructs frequently, and it makes it much easier to change types, if that is ever necessary, or adapt constructs to new types.
