Understanding arrays

Local array of array of any &AAAny = CreateArray(CreateArrayAny(1, 2), CreateArrayAny("hi"), CreateArrayAny("there", "2", "dsfds", "444444dsfds"));

Local array of array of number &AAnumber = CreateArray(CreateArray(1, 2), CreateArray(777, 555, 55999, 22), CreateArray(3, 888, 560, 7124));

Local array of array of array of number &AAnumber_3 = CreateArray(CreateArray(CreateArray(1, 2), CreateArray(CreateArray(1000, 2000)), CreateArray(CreateArray(777, 555, 55999, 22)), CreateArray(CreateArray(3, 888, 560, 7124))));

rem 444444dsfds;
WinMessage(&AAAny [3][4]);

rem 7124;
WinMessage(&AAnumber [3][4]);

rem 2000;
WinMessage(&AAnumber_3 [1][2][2]);
