An array represents an indexed collection of elements of the same type (called the
base type). Because each element has a unique index, arrays, unlike sets, can
meaningfully contain the same value more than once.

Array types are denoted by constructions in the following form:

array[index_start .. index_end] of type

Each of the elements of an array is numbered from 

index_start

through

index_end

. The specifier 

index_start

can be omitted along with dots, in which

case it defaults to zero.

Every element of an array is of 

type

and can be accessed by specifying array name

followed by element’s index within brackets.

Here are a few examples of array declaration:

weekdays : 

array[1..7] of byte;

samples  : 

array[50] of word;

// Now we can access elements of array variables, for example:

samples[0] := 1;
if samples[37] = 0 then ...

Constant array is initialized by assigning it a comma-delimited sequence of values
within parentheses. For example:

// Declare a constant array which holds number of days in each month:
const

MONTHS : 

array[1..12] 

byte =

(31,28,31,30,31,30,31,31,30,31,30,31);

The number of assigned values must not exceed the specified length. The opposite
is possible, when the trailing “excess” elements are assigned zeroes.

For more information on arrays of 

char

, refer to Strings.
