[comp.lang.ada] Ada type question

keith@telesoft.UUCP (Keith Shillington @prodigal) (01/06/89)

-- To define an array type:

type x is array(integer range 1..10) of character;

-- Would define a ten element array of characters.  "Better" Ada would be:

subtype x_range is integer range 1..10;
type x is array(x_range) of character;

-- More flexible would be:

type x is array(integer range <>) of character;

subtype working_x_range is integer range 1..10;
subtype large_x_range is integer range 0..1000;

subtype working_x is x(working_x_range);
subtype large_x   is x(large_x_range);

-- Then you can define your index variables of an appropriate type to work
-- with the objects that you define of the various x subtypes.

I posted a question here a few days ago about Ada TYPEs, but it seems
many people didn't understand the actual problem I was having.
I have since then found the answer that I needed (but not wanted)

what I originally asked was (is there any way to do this)

make a type definition that looks something like this:

type X is (array, .....)

i was not trying to define something of an array.  What I wanted
was a new type "X" that could take on a value "array" or whatever
else is in the list. But the problem was that array is a keyword
(reserved) therefore I couldn't do what I wanted, the only alternative
that I have been able to come up with is:

defining X as an array of string
x(1):= "array     "
x(2):= "whatever  "
.
.
.

Thanks for all of the responses!

Just thought I would clear up some of the confusion to my original 
question
