To declare an array constant, enclose the values of the array's elements, separated by commas, in parentheses at the end of the declaration. These values must be represented by constant expressions. For example,
const Digits: array[0..9] of Char = ('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');
declares a typed constant called Digits that holds an array of characters.
Zero-based character arrays often represent null-terminated strings, and for this reason string constants can be used to initialize character arrays. So the previous declaration can be more conveniently represented as
const Digits: array[0..9] of Char = '0123456789';
To define a multidimensional array constant, enclose the values of each dimension in a separate set of parentheses, separated by commas. For example,
type TCube = array[0..1, 0..1, 0..1] of Integer;
const Maze: TCube = (((0, 1), (2, 3)), ((4, 5), (6,7)));
creates an array called Maze where
Maze[0,0,0] = 0
Maze[0,0,1] = 1
Maze[0,1,0] = 2
Maze[0,1,1] = 3
Maze[1,0,0] = 4
Maze[1,0,1] = 5
Maze[1,1,0] = 6
Maze[1,1,1] = 7
Array constants cannot contain file-type values at any level.
