A value of the subtype can be assigned to variable of type
STANDARD.INTEGER, a value of the type cannot. (Unless you do an
explicit conversion.) The principal advantage to using many different
integer types is that the compiler will prevent you from accidently
assigning Apples to Oranges.
Some people object to all those #$@#%*! messages from the
compiler, but software engineers know that it saves a lot of money to
find the bugs as early as possible.
