Arrays in Ada start at the index based on the index type of the array. You can even use an enumeration type as the index:

    type Day is (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday);
    type Hours is array (Day range <>) of Natural;

    V : Hours (Monday .. Friday);

Which index type you should use depends on the problem that you're trying to model. You can find out the lower/higher end of a type/variable with the 'First and 'Last attributes.

IIRC there's an RFC though to force the lower end of the index to a certain value like 1 or any other number/enum.

Wow, I never really looked at Ada code. Been using VHDL for the past 2 years a lot and when I looked at your code I was like: 'huh strange, this looks a lot like VHDL'.

Turns out both were invented by the DoD.

>Due to the Department of Defense requiring as much of the syntax as possible to be based on Ada, in order to avoid re-inventing concepts that had already been thoroughly tested in the development of Ada,[citation needed] VHDL borrows heavily from the Ada programming language in both concept and syntax. - https://en.wikipedia.org/wiki/VHDL

Maybe I should pick up Ada soon. That could be a fun journey! (I really love writing VHDL)

I always wonder why such fundamental features were not adopted by all languages.
