-- To define an array type:

type x is array(integer range 1..10) of character;

-- Would define a ten element array of characters.  "Better" Ada would be:

subtype x_range is integer range 1..10;
type x is array(x_range) of character;

-- More flexible would be:

type x is array(integer range <>) of character;

subtype working_x_range is integer range 1..10;
subtype large_x_range is integer range 0..1000;

subtype working_x is x(working_x_range);
subtype large_x   is x(large_x_range);

-- Then you can define your index variables of an appropriate type to work
-- with the objects that you define of the various x subtypes.
