If I have a class like:
program myclass;
 type
   THelloWorld = class
     procedure Put;
   end;
 var
   HelloWorld: THelloWorld;
 procedure THelloWorld.Put;
 begin
   WriteLn('Hello, World!');
 end;
 begin
   HelloWorld := THelloWorld.Create;
   HelloWorld.Put;
   HelloWorld.Free;
 end.
 

How do I use that class in another program?
