subtype M is Character range 'A' .. 'Z';
C: array (M) of Natural;
I: integer : =1;
**************************************
What can be inferred from the following calls (compilation and then
execution ) ?
C('i'):=1;
C('I'):=I;
C('I'):='I';
C(I):=I;
C('I'):=0;

natural is a subtype of integer. As long the value of I is an natural it
should work. Otherwise it should throw an exception: Constained_error.

Looks ok.Hello Celinio!
Why not try it on your compiler?

Personally I would infer that you are trying to get your homework done
by someone else.
