Please this is not "the RosAsm" approach, this is my approach to RosAsm.
You point about not having type info is incorrect.

SizeOf_TComposite3DObject says : it inherited from TComposite3DObject
+ its says something about the size of the inherited data.

similarly : SizeOf_Double is to also have type information. Its long for
Double. And it speaks the truth.

Oh you ment type info to the assembler..... Oki. Sofar that has not been
needed. I need only to make sure that I wrote it correctly. And test. In
real life, it works very well. As said before this but a blip on my
timetable.

Well. Can we start to remember soon that this is an assembler forum ?
