When OpenEdge needs a memory-mapped r-code segment, it executes the segment directly from shared memory. OpenEdge does not store active memory-mapped r-code segments in the execution buffer. Nor does it swap non-active segments to the r-code swap file. OpenEdge relies on the operating system to manage the swapping of r-code segments in and out of shared memory.

Note: The AVM swaps codepage-converted text segments for procedure libraries from the execution buffer to the r-code swap file and reloads the converted text segments from the swap file instead of the library when necessary.
