In Delphi, arrays allow a developer to refer to a series of variables by the same name and to use a number (an index) to tell them apart.

In most scenarios, you declare an array as a variable -- thus allowing for array elements to be changed at run-time.

Sometimes, however, you need to declare a constant array -- a read-only array.

You cannot change the value of a constant or a read-only variable.

Therefore, while declaring a constant array you must also initialize it.

Example

type   

     TShopItem = record     

          Name : string;     

          Price : currency;   

     end;

const   

     Days : array[0..6] of string =    (     

          'Sun', 'Mon', 'Tue', 'Wed',     

          'Thu', 'Fri', 'Sat'    ) ;   

     CursorMode : array[boolean] of TCursor =  (

           crHourGlass, crSQLWait ) ;   

     Items : array[1..3] of TShopItem = (

          (Name : 'Clock'; Price : 20.99),     

          (Name : 'Pencil'; Price : 15.75),     

          (Name : 'Board'; Price : 42.96)    ) ;

This code declares and initializes three constant arrays, named: "Days," "CursorMode" and "Items."
