What's the difference between...

[ucivax!gateway@ucbvax.Berkeley.EDU (Kenneth Anderson)]

these two type declarations:

type Placement is range 0 .. 10;

subtype Placement is INTEGER range 0 .. 10;


The reason I ask this, is that I have the duty here at U.C. Irvine of teaching
the students of an Intro to Software Engineering course enough Ada for them
to do their homework assignments.  I get two 1.5 hour lectures to do this.

One of my students asked what is the difference between the two type
declarations.

My answer was "Not much.  I'll get back to you on what the conceptual
difference is."

So I would like to tell him at the next lecture what the difference is.

Can someone help me out?

Thanks in advance,

Ken
