Comments are completely discarded during compilation. You will never recover the "why" behind the code, only the "how."
The r‑code file is proprietary to Progress Software. Its internal structure differs from compiled formats used by traditional compilers such as C, C++, or Java. This file contains not only executable instructions but also debugging symbols, line number mappings, and other meta‑information essential for runtime operations. However, because r‑code is designed to be human‑readable, recovering source from an .r file is anything but straightforward.

Whether the target app was (e.g., using ProGuard/R8)?
There is no official "Decompile" button in the OpenEdge Application Server. To get your code back, you generally have to rely on third-party tools or "disassemblers" that interpret the R-code segments and attempt to reconstruct the original ABL logic. The "Link" Aspect: How Files Connect

To prevent future data loss, immediately check your recovered files into a Git or SVN repository.
An .r file is the compiled, binary form of an ABL (Advanced Business Language) program. It is created by the OpenEdge compiler from human‑readable source files ( .p for procedures, .w for windows, .cls for classes). The runtime environment loads these R‑code segments into memory and swaps them to a temporary .rcd file when space is needed. Comments are completely discarded during compilation
