A recent discussion on RFE 715 led to the question of whether or not
ooRexx 4.2.0 and 5.0.0 could coexist on a system. I am starting this
thread to hopefully expose the discussion to a larger audience. As my
experience is restricted to Windows systems, I am restricting the
subject to that environment but the question certainly applies to
non-Windows systems as well. Anyone with expertise in those
environments should start a parallel thread to extend the discussion to
them as well.
I guess the first question that comes to mind is why one would want to
have both 4.2 and 5.0 on their system at the same time. One scenario
that comes to mind is the case where a system is being used in a
production environment using 4.2 but there is interest in moving to 5.0
when it becomes GA. So having the ability to test the production
programs under 5.0 before that while still running the 4.2 production
programs would be beneficial and accelerate the time to needed to make
the transition once 5.0 goes GA. I'm sure there are other cases as well
and I would be happy to hear them.
So the simple answer to the question was provided by Rick: "Actually,
with the changes to how rxapi communicates in 5.0.0, they coexist quite
nicely. They can both be active at one time." As always, the devil is in
the details! I'll get into those details in the next post.
