Progress provides built-in attributes via the RCODE-INFO system handle. While this won't give you the source code, it allows you to extract vital metadata such as: The version of OpenEdge used to compile it. The MD5 signatures of the buffers. Embedded CRC values for database tables.
The short answer is , but with several technical caveats. Here is everything you need to know about the process, the tools available, and what to expect from the output. Understanding the Progress .r File decompile progress .r file
Because R-code retains much of the original logic structure and metadata to interact with the database, it is technically possible to reverse-engineer it. Methods to Decompile .r Files 1. Using the RCODE-INFO Handle (Built-in) Embedded CRC values for database tables
In the OpenEdge environment, a .r file is the compiled "R-code." Unlike some languages that compile to machine code, R-code is a platform-independent p-code (pseudo-code) that runs on the Progress AVM (Advanced Business Application Virtual Machine). Understanding the Progress
A .p file that contains the logic, database triggers, and procedure calls.
If you need to , your best bet is a professional tool like Joanju. While you won't get your original comments back, the recovered logic is usually enough to save hundreds of hours of manual rewriting.
