#ObjectPascalNotes

type
  TAllYearTemps = array [1..24, 1..31, 1..12] of Integer;

var
  AllYear: TAllYearTemps;

Static arrays immediately take up a lot of memory (in the case above on the stack), which should be avoided. The AllYear variable requires 8,928 Integers, taking up 4 bytes each, this is almost 35KB. Allocating such a large block in the global memory of on the stack is really a mistake. A dynamic array, instead, uses the heap memory, and offers much more flexibility in terms of memory allocation and management.

#ObjectPascalFeatures

var 
  di: array of Integer;
  i: Integer;

begin
  di := [1, 2, 3];       // initialization
  di := di + di;         // concatenation
  di := di + [4, 5];   // mixed concatenation

  for i in di do
  begin
     Show(i.ToString);
  end;

end.

These features to dynamic arrays were added in Delphi XE7
