'Image returns a string whose first character is a space if the
argument is not negative.  So if N =3D 12, then Integer'Image(N) =3D "
12"---i.e. 3 characters.  That won't fit in the two-character slice
you're trying to put it in, so you get a Constraint_Error.

But just getting rid of the space doesn't work either.  If N =3D 1, then
Integer'Image(N) =3D " 1", and if you were able to trim off the space,
the result would be "1", and you'd still get a Constraint_Error.  When
you assign a slice like this, the left and right sides must be the
same length.

There are a number of ways to do what you want, but I'd suggest
looking at the Ada.Strings.Fixed package, especially the Move, Trim,
and Tail routines.

Hope this helps,
