Totally agree with you. JCL is what it is. The data set I/O classes are
even more pathetic which is why I wrote https://github.com/daveyc/pyzfile

I certainly hope that whatever the industry is doing that gets adapted to
the mainframe does so much more cleanly than, say, Python...
Like what? Have you ever tried to write a TCP server in REXX?
The absolute abortion that is Python's idea of replacing JCL makes COBOL
look like APL.
I haven't seen that. Can you post a link?

I think 99% of the folks on this forum want a language that can run in
a TSO/ISPF environment hosted in PDS data sets. Lua can do that and it's
orders of magnitudes faster then REXX with the advantage of package
management. The next gen guys don't use TSO/ISPF and they're going to
use
Python and couldn't give a hoot about NetRexx.
NetRexx can and does, using the IBM jzos classes, which are delivered
with its JVM’s.
Hmm, I don't think so. NetRexx programs can not reside in PDS data sets.
I don't get the point of NetRexx.
They can do a lot more with conventional MVS than LUA, I am sure.
Don't agree. Lua4z has a heap of integrations including TSO/ISPF without
VDEFINE. And you can write packages and applications using PDS data
sets. REXX is impoverished in this respect and you can't share state or
data structures between modules.

Not that anyone would do that, of course, being so much easier with
ISPF
and Rexx and their shared variable pool. I have built dialogs in COBOL
and
PL/1 but nothing beats Rexx for that, having not to VDEFINE everything
first.
That's subjective. I find it much easier to write code in Lua. A
programming language that supports OO, meta-programming, functional
programming and co-routines with just 20 reserved words is a thing of
absolute beauty and a testament to the designers. REXX is a niche
language that's only used to any great extend on mainframes and it's
popularity is constantly eroding. The mainframe needs to keep pace with
the industry.
