一句话：介绍 PACMPL 的办刊定位、与 SIGPLAN 的合作关系及其开放获取承诺。
本文是 PACMPL（Proceedings of the ACM on Programming Languages）的编辑寄语。文章说明 ACM Proceedings 系列旨在呈现计算机科学各领域由 SIG 代表的高质量研究，而 PACMPL 聚焦编程语言研究的各个方面，从语言设计到实现，从数学形式化到实证研究。期刊与 ACM SIGPLAN 紧密合作，并承诺让高质量的同行评审编程语言研究在获取和使用上不受限制。该文不提出具体研究问题、技术方法或评估结果，属于期刊范围与政策的介绍性说明。
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.
