Hi, Doing some research on the above and found this in the KB; knowledgebase.progress.com/.../20922 3. R-code Version Change A recompile will always be required when moving to a different Major OpenEdge release as the r-code version always changes between major versions. Between Minor OpenEdge releases, forward-compatibility is guaranteed for r-code, but not backwards-compatibility. Code compiled in a lower minor release will run in a higher minor release; the other way around is not guaranteed. Between Minor versions, the r-code version number may remain the same, but using new ABL features added in a later minor release will break compatibility with earlier minor versions. Is this correct? Backwards compatibility is not guaranteed between minor RCODE versions? Many Thanks, Mark.
