SonarSource provides static code analysis for PL/I projects. Based on our own technology, it analyzes PL/I code and find Code Smells, Bugs, and Security Vulnerabilities. As with everything we develop at SonarSource, it was built on the principles of depth, accuracy, and speed.
SonarSource's PL/I analysis covers some of the well-established quality standards. This capability is available in Compuware Topaz and IBM IDz for developers (SonarLint) as well as throughout the development chain for automated code review with self-hosted SonarQube or on-line SonarCloud.
SonarSource's PL/I analysis provides the ability to write custom rules.
