You can run a simple ABL script using the RCODE-INFO handle:
.r files are compiled ABL (Advanced Business Language) bytecode from Progress Software's OpenEdge platform. These are not designed to be decompiled in the traditional sense. Progress intentionally does not provide a decompiler. You can:
ls() # See all objects: functions, data frames, lists, etc. decompile progress .r file
Unlike some compiled languages that translate directly to machine code, Progress uses this p-code which is executed by the Progress runtime engine (the "Virtual Machine"). Why Decompile?
: If you are trying to understand the code for debugging, you can generate a debug listing You can run a simple ABL script using the RCODE-INFO handle:
Open the .r file in a hex editor (like HxD) and look at the right-hand text preview pane. You will see plain-text references to database tables, fields, and external .p programs called by the file. Major Challenges and Obstacles 1. OpenEdge Version Compatibility
Contains the formulas and literal values used in calculations. You can: ls() # See all objects: functions,
Stores hardcoded text strings, such as UI labels and error messages.
# Open a text file connection sink("decompiled_source.R") # Loop through all objects and print their source code for (obj_name in ls(env)) cat("\n\n# --- Object:", obj_name, " ---\n") print(env[[obj_name]]) # Close the file connection sink() Use code with caution. 3. Decompiling R Bytecode
