Echoing what others have said, upward OS compatibility for compiled and linked applications is a hallmark of MVS and its descendants. I would be stunned if you had a problem with the COBOL apps. Trust but verify: you might want to run a test or two on the new hardware. And it's not the end of the world, right? You/they *could* recompile a failing application?
Is Easytrieve interpreted or compiled? My recollection is interpreted. If so, it's hard to see how there could be an upward compatibility problem.
