I wish to manipulate very large integers with values in the 
trillions.  This would require a 64 bit integer type, so to maintain 
portability I specify a new type using range and let the compiler do 
the right thing.

type BigInt is range 1..10_000_000_000_000;

I then wish to get and put these values, so I instantiate 
Integer_IO.

package BigInt_IO is new integer_IO(BigInt);

My program consists of three parts: the main body, a package spec 
and a package body (the package containing all the subprograms and 
functions).

1) Is this the way to do it, or is there a preffered way?

2) Where, speciffically, do I place the above two lines (and the 
associated "with" line) so that I can BigInt_io.get from the main 
body and the package subprograms as well?

So far, every place I have tried has offended the compiler.  And my 
text books have been of little help (I have more on order).

Thanks for the help!
