Going from an older release to a newer one is a piece of cake
(especially as in this cas where you are not crossing the CISC to RISC
barrier).  Just save on the V3R7 system and restore on the V4R1.  Now
note that if you do recompile, you might get a little bit better
performance, but it is not required at all.  But you can save objects on
a S/38 and restore them to V4R1 - and they will run fine!

The biggest thing to check is that you have all objects needed for an
application and that there are no objects currently on the system that
have the same library & name as objects you are restoring (of course).  

If you haven't moved a similar application to V4R1, you'll want to test
- there is always the chance of some defect being uncovered when you go
to a new release.  Also, check out the "Memo to Users" for V4R1 for any
changes to the OS that might affect your application.

In any case, the save and restore shoulkd be a snap - you could even use
SAVRSTLIB (i.e. ObjectConnect), if the library is relatively small and
you have a comm link between the two systems.  Otherwise, just make sure
your tape devices are compatible and off you go!
