<> means the range is undertmined at type declaration time.
when you then define a variable this type, then you need to specify
the range. This way you can use the same type to define different
objects of that type of varying ranges. so you dont have to have
to declare a new type everytime where is the only difference
between them is the value of the range. this is called generic type.

yes, you can change INTEGER above. this is the type of the index. which
can be any scalar type.

check some of the Ada text books for examples.
