R-code Features and Functions

R-code is the intermediate binary code that OpenEdge generates when it compiles ABL (Advanced Business Language) source files. This is the code that OpenEdge actually runs when it executes a procedure or class, whether from session compiles or from permanently generated r-code (.r) files.

Note: Whether the source code is an ABL procedure or ABL class, it compiles into r-code. For the purposes of this topic, procedure and class files are equivalent.

OpenEdge provides a dynamic r-code execution environment, as well as integrity and security mechanisms to ensure that your r-code is running in a compatible environment.
