5D - Multidimensional Arrays (author: Tao Yue, state: unchanged)
You can have arrays in multiple dimensions:
type
datatype = array [enum_type1, enum_type2] of datatype;
The comma separates the dimensions, and referring to the array would be done with:
a [5, 3]
Two-dimensional arrays are useful for programming board games. A tic tac toe board could have these type and variable declarations:
type
StatusType = (X, O, Blank);
BoardType = array[1..3,1..3] of StatusType;
var
Board : BoardType;
You could initialize the board with:
for count1 := 1 to 3 do
for count2 := 1 to 3 do
Board[count1, count2] := Blank;
You can, of course, use three- or higher-dimensional arrays.
