eXplain
eXplain is a specialized code-analysis and legacy-system evaluation tool from PKS Software GmbH, designed to deeply analyze, map, document, and assess legacy applications, especially on mainframe platforms such as IBM i (AS/400) and IBM Z, so organizations can understand what lives in their software, how it’s structured, and what parts are worth keeping, refactoring or retiring. It imports existing source code into an independent “eXplain server”, no need to install anything on the host system, then uses advanced parsers to examine languages like COBOL, PL/I, Assembler, Natural, RPG, JCL, and others, along with data about databases (Db2, Adabas, IMS), job-schedulers, transaction monitors, and more. eXplain builds a central repository that becomes a knowledge hub; from there, it generates cross-language dependency graphs, data-flow maps, interface analyses, clusterings of related modules, and detailed object-and-resource usage reports.

Expedient
A multi-cloud approach designed to optimize application placement for your entire IT estate, with a full stack of universal management services designed to accelerate your transformation journey. Your enterprise workloads and applications are ready for a migration to the cloud, but a move to a hyperscale cloud provider requires your teams to learn entirely new platforms, demands potential refactoring of your applications, and doesn’t provide you with the inherent security and white-glove managed services you need to keep your business risk-free and running seamlessly.

Assembler Code Refactoring
Rocket Assembler Code Refactoring is a specialized modernization solution that automatically restructures legacy Assembler code into structured pseudocode or modern languages such as COBOL, C, or Java without altering external behavior, enabling faster, lower-risk modernization and improved maintainability. Assembler code is notoriously dense, poorly documented, and supported by a shrinking pool of specialists, making maintenance slow, costly, and error-prone; this product addresses those challenges by delivering semantics-preserving, auditable transformations that reduce outages and secure modernization without sacrificing stability. Its fully automated core engine uses mathematically guaranteed logic equivalence to eliminate conversion risk, dramatically accelerating projects while ensuring that refactored outputs are semantically identical to the original code.
