Load and execute r-code from a file

When loading r-code from an operating system file in a directory, OpenEdge opens the r-code file, loads the required r-code segments into local memory, and closes the file.

When executing r-code from an operating system file, OpenEdge accesses and executes the r-code segments in the execution buffer in local memory. OpenEdge also swaps segments to and from the r-code swap file, as necessary.
