You can have arrays in multiple dimensions:
     type
        datatypeidentifier = array [enum_type1, enum_type2] of datatype;
        datatypeidentifier = 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 go into three- or higher-dimensional arrays.
