摘要
A.R. Meyer和K. Sieber(第15期ACM)。计算机协会。on Principles of Programming Languages, 1988, p.191-208)给出了一系列程序的例子，这些程序在操作上是等价的(根据块结构类algol程序的预期语义)，但在传统的指称语义中没有给出等价的表意。他们提出了对指称语义的各种修改，以解决其中的一些差异，但不是全部。目前的作者接近同样的问题，但从操作而不是外延的角度来看。他们提出了一种新的程序推理逻辑的一阶部分，并用这种逻辑证明了Meyer-Sieber例子的等价性。
References, local variables and operational reasoning
A.R. Meyer and K. Sieber (Proc. 15th ACM. Symp. on Principles of Programming Languages, 1988, p.191-208) gave a series of examples of programs that are operationally equivalent (according to the intended semantics of block-structured Algol-like programs) but are not given equivalent denotations in traditional denotational semantics. They propose various modifications to the denotational semantics that solve some of these discrepancies, but not all. The present authors approach the same problem, but from an operational rather than a denotational perspective. They present the first-order part of a new logic for reasoning about programs, and they use this logic to prove the equivalence of the Meyer-Sieber examples.<>
