I kinda like Mike's suggestion, to have
a new set of functions to support IP6. Now if the newer IP6 stuff
can work correctly in IP4 or IP6 then I think we have a winner.
Existing stuff would continue to work under IP4, and when an
applications code is converted to use the new IP6 functions it
might still work in an IP4 only environment. Have a newer set of
functions also addresses Mark's comment of being more object
oriented, rather than "procedural"...
That way I do not have to change the ooRexx programs that I have
already written that use IP4.
When I want to support IP6, I can modify the code as needed to
make use of the newer IP6 support. With separate libraries, as a
designer, I can choose which way I want to go....
I see some problems with requiring a newer version of ".net",
because I know of a number of companies that are not ready to
convert to newer releases beyond WINXP, even though they will not
have any official "support". Sometimes, this is a financial issue
(new hardware, new software, training, etc.), and in other cases
it is because they do not have the staff to oversee an orderly
Requiring a newer version of .NET might make some applications to
be not available on an older system and/or a older application to
not be available on a newer version of Windows. You also have the
"special" case of anybody who uses WINXP under a virtual machine
to support applications that have not been converted to a newer
Windows environment (or that are not available under Linux).
Compatability issues can be, and frequently are, complex - For
Instance, I have found a number of little applications that say
they work under Windows 8.1 - and they don't, unless the target
system has a real touch screen - particularly error message pop-up
screens that are longer then the laptop's screen height with an
"OK" button at the bottom of the window.... With a touch screen
you can "slide" the window up, but unless the designer provided
for the old scroll bars as well, you can't scroll the windows with
your mouse or cursor buttons.
This also applies to Linux environments, which as we know, are not
all the same... i.e. Ubuntu's newer screen manager
or Gnome 2 -vs- Gnome 3 -vs- KDE - vs- whatever.
My vote? consider doing the IP6 under a newer set of functions.
