Warning, this code has not been compiled (it's homework, so that's
your job :).
procedure Homework is
Array_Length : Integer;
type Ustring_Array is array (Integer range <>) of Ustring;
begin
-- Use Text_IO or something to set Array_Length here!
declare
My_Array : Ustring_Array (1 .. Array_Length);
begin
-- do stuff with My_Array
end;
end Homework;
The basic idea is that an array can be declared in an inner block, and
the length of the array can be set by a variable.
