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