一句话：介绍 PACMPL 期刊的定位、与 SIGPLAN 的合作及开放获取承诺。
本文是 PACMPL 的编辑寄语，不报告具体研究。它说明 Proceedings of the ACM 系列发表 ACM SIG 各领域的高质量研究，而 PACMPL 聚焦编程语言的设计、实现、数学形式化与实证研究等所有方面。期刊与 SIGPLAN 紧密合作，致力于使高质量的同行评审编程语言研究在访问和使用上均不受限制。全文未提出研究问题、方法或评估，属于期刊定位与出版政策的说明。
The Proceedings of the ACM series presents the highest-quality research conducted in diverse areas of computer science, as represented by the ACM Special Interest Groups (SIGs). The Proceedings of the ACM on Programming Languages (PACMPL) focuses on research on all aspects of programming languages, from design to implementation and from mathematical formalisms to empirical studies. The journal operates in close collaboration with the ACM Special Interest Group on Programming Languages (SIGPLAN) and is committed to making high-quality peer-reviewed scientific research in programming languages free of restrictions on both access and use.
