While R-code is generally portable, the internal structures can differ between 32-bit and 64-bit compiled files, which can trip up older decompilation scripts.
If you only need to find a specific hardcoded string, file path, or SQL query inside a .r file, you can use a hex editor or a "strings" utility. Since Progress doesn't always encrypt string constants in the compiled file, you can often peek at the text values without a full decompilation. Limitations and Challenges
you are targeting for this recovery?
This is mostly useful for debugging version mismatches rather than code recovery. 2. Commercial Decompilers (The Most Effective Way)
If you’ve ever found yourself with a compiled Progress OpenEdge file (a .r file) but no original source code ( .p or .w ), you know how stressful that can be. Whether it’s due to a lost repository, a legacy system hand-off, or an accidental deletion, the question is always the same:
Comments are lost forever (they aren't compiled into the .r file), and local variable names may sometimes be replaced with generic identifiers (like var001 ) if the debug information was stripped during compilation. 3. Hex Editors and Strings
Before decompiling, ensure you have the legal right to do so. Reversing proprietary software can violate EULAs (End User License Agreements). Decompilation is generally reserved for: Recovering your own lost IP. Security auditing and vulnerability research. Interoperability fixes for legacy systems.

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.
