Dave -
I am replying to you and to our developer mailing list so that this
conversations is documented.
The first thing you need to do is to join the ooRexx developer mailing list at
https://lists.sourceforge.net/lists/listinfo/oorexx-devel. This will get you
into a conversation with all the active developers. Rick McGuire is our
architect and he also has the most CMS experoence of any of our group. If you
want to tackle CMS first then he is the person you need to create a plan with.
We can all help you with C/C++, Subversion. tools and SourceForge issues. We are
trying to maintain a single source tree for all platforms and we will want to
continue that with an new platforms. There will be issues obviously with ASCII
to EBCDIC conversions and other such issues but Rick and myself can guide you
through those issues.
After you join the mailing list we can begin in ernest. We look forward to your
contributions.

Hi, David.
You're in luck...I'm an expert CMS developer. I know a some C, having
written a few short and simple programs (fwiw, I dislike C) and
practically no C++ at all, so I would need help with things like "what
does this C++ code really do?". I've used ooRexx on both Intel Linux and
zLinux quite a bit, but mostly in the "classic" style.
I believe that the port of ooRexx to CMs will be the more difficult one
simply because the CMS environment is so radically different from all of
the others. At least with z/OS, you can start with a port of USS, with
all of it's normal Unix style tools and environment; CMS offers no such
comparable environment.
The other main issue with ooRexx on CMS is that ooRexx, being coded in
C/C++, will require the support of LE; that, in it self, isn't the
problem because CMS has the latest version of LE available; it's that LE
itself isn't all that well integrated into the CMS world....you can not,
for example, code things like CMS Pipeline stages, subcom handlers, or
RSK routines in any HLL that requires LE. You can write standalone
programs that require LE with few if any restrictions.
We do have both z/VM 5.4 and 6.1, plus the latest z/VM C/C++ compiler
here as well as HLASM R6 and a bunch of other IBM CMs development tools,
so that should pose no problem.
What would you like to do first?
Happy Holidays as well.

We really have two problems in getting ooRexx ported to z/OS and CMS.
1. Hardware to develop the ports.
2. Developer expertise in those environments.
We have had several offers for problem one but practically no offers on
problem two. None of the current development team have the knowledge to
do ports on these platforms and we need that before we can even proceed
with any planning.
If you know volunteers with even partial knowledge in this area we would
be more than happy to have them join our team.
Thanks

David,
I keep looking for mainframers interested in shepherding an ooRexx
port to z/VM and z/OS. Would you like to contact Dave and see if he
is willing to help?

Hi, Chip.
That's the Open Source evolution of IBM Object REXX, supported by a
team of developers lead by Rick McGuire (an original developer of IBM
OREXX), is freakishly powerful, and currently runs on every major
platform (32/64-bit Windows, Mac, UNIX/Linux, looking into Android) --
except z/VM and Z/OS.
Believe me, it's not for lack of desire, interest, or love of CMS. We
simply don't have access to the necessary resources (hardware and
wetware) in order to effect a proper port of the (predominately C/C++)
code.
If you would be interested in contributing in some way to the effort
to port ooRexx to IBM's Flagship Operating System (and/or z/OS ;-)
please go to the ooRexx website www.oorexx.com and contact the Project
Manager, David Ashley.
I can make the hardware and software resources need to do a port of
ooRexx over to z/VM (CMS, that is), as well as z/OS. Please pass that
along to the proper folks.
The "hard" part of this port might focus on the fact that CMS is such a
different environment that the ones you mentioned....for example,
process and thread support.
Happy Holidays, too.
