maybe because your classes don't descend from any other class that owns 
a "create" or "free" methods...

If you use classes, out of the top of my head, I could say that an 
instantiation, like

var C: MyRecordConvertedToClass;
...
C.X = 10;
C.Y = 20;

should be enough.

Otherwise, you had better define a base class, with constructor and 
destructor, overriding them as needed in every derived class.

Anyone correct me if I am wrong in this statement...
