Tue Sep 02 Program Verification Using Counterexample-guided Abstraction Refinement Winskel Chapter Two: Introduction to operational semantics
Hoare's Hints On Programming Language Design (shorter than it looks)

Thu Sep 04 A Simple Imperative Language
Operational Semantics
HW 0 Due Choose at least one of these three:
1. Wegner's Programming Languages - The First 25 years
2. Wirth's On the Design of Programming Languages (bonus points if you mistakenly choose this one just because it has the lowest page count)
3. Nauer's Report on the algorithmic language ALGOL 60 (the language that Hoare said was an improvement not only on its predecessors but also on nearly all of its successors)
Cobbe and Felleisen's Environmental acquisition revisited (optional, recent paper -- POPL 2005, uses operational semantics on page 7, figure 11, just skim to that figure and see if you recognize it)
Chen and Tarditi's A simple typed intermediate language for object-oriented languages (optional, recent paper -- POPL 2005, uses operational semantics on page 9, figure 14, just skim to that and note the non-standard syntax -- but you should be able to interpret the (H; V ; x : t = v in e) rule, for example)
Plotkin's A Structural Approach To Operational Semantics (optional, basically a textbook, see chapter 2 for another take on what we're covering in class)
