Example code : Store 3 Int64 values in memory and navigate through them
var
  int64Ptr : PInt64;
  a : TDateTime;

begin
  // Allocate storage for three Int64 variables
  GetMem(int64Ptr, 3 * SizeOf(Int64));

  // Fill out these Int64 variables
  int64Ptr^ := 1;
  Inc(int64Ptr);
  int64Ptr^ := 22;
  Inc(int64Ptr);
  int64Ptr^ := 333;

  // Now display these values
  Dec(int64Ptr, 2);
  ShowMessageFmt('Value 1 = %d',[int64Ptr^]);
  Inc(int64Ptr);
  ShowMessageFmt('Value 2 = %d',[int64Ptr^]);
  Inc(int64Ptr);
  ShowMessageFmt('Value 3 = %d',[int64Ptr^]);
end;
