Much the same as our QuestView product uses a number of OS features that were added at V4, and yet can get along just fine (minus the functions that use those OS features) on (if we still had V2 compilation capapbility) a V2 box.

As far as I know, its not exactly documented what a program would do at Activation time, if some imports are not resolvable (or I didn't find the documentation). Deferred activation would not help for most boxes, because they are running older releases (how does this react in case of not existing exports?, where is it documented?) . I would use binding at runtime by API QLEAWI, it will give full controll and deferr any error situation untill call time and all work could be done in an Activation routine only called once. For not resolvable imports a dummy routine could be called, producing a warning in the Joblog and this would work as well in case the SRVPGM does exist only having a subset of procedures.
