It's illegal to declare a variable of type String, unless you either
initialize it, or give bounds.  E.g. "Message: String := ...;" or
"Message: String(1..50);".

Image is an attribute of types, not variables.  E.g. "Integer'Image(I)".

What you want is something like:

    Message: constant String := "The total is" & Integer'Image(I) 
				& " out of 100";

Note that the 'Image attribute evilly adds an extra space (if I is
positive), so I didn't put a space after "is".

In my own code, I write an Image function, which avoids the annoying
extra space, and has lots of options like allowing hexadecimal, and
putting in underscores every 3 characters, etc.  All with defaults, of
course, so "Image(I)" does something reasonable.
