[fpc-pascal] allocating memory for records

[Leonardo M. Ram�]

You also can create an object an instantiate it in the initialization section of the unit an
finalize at the end, if you use this unit, the instance of the created object will not lose it's
value:

type
  MyRec = class
  public
    a: integer; /* very clear */
    b: string; /* not clear, how much bytes are needed? */
  end;

var
   myRecVar: MyRec;

initialization
  myRecVar := MyRec.Create;
  myRecVar.a := 10;
  myRecVar.b := 'Hello World!';

finalization
  myRecVar.Free;
