Re: Upcoming spring 2021 RPG enhancements announced today -- RPG400-L

I've found so far the best method for me is with a web service, then using
GETURI to call it. But, the weak link in the chain is making sure SSHD
server is up and running.

Works great when it works, but when it doesn't you're scrambling for what
magic lines/commands to copy and paste to fix it... haha..

Just last week a customer applied PTFs and SSHD wouldn't start, so the node
service we were calling failed. The only way I could find the error as to
why SSHD wouldn't start was using the QSH command to start it. It was
missing a specific key file that it seems really isn't required any more.
So applying a PTF seems to have removed that key, but it didn't update the
config file looking for that specific key. hahah..

Yes... I wish there was a better way. As far as liking node, I've been
heavy JS for years so it was natural for me. I never got into Perl, php,
etc. But in my old days did some C, Pascal, Modula II, etc. :) Either
way, it's mainly just learning a new syntax.

it is _way_ more complex to implement than (say) Java was - JNI was already
an architected interface and Java sorta runs in ILE. with the PASE stuff
the barriers and difficulties are far greater. If you follow the chats on

P.S. Funny you should like node. I look at it and all I can see is the
worst of C and C++ but with knobs on. But that's just me. Pythong on the
other hand is much nicer.

What RPG really needs these days is the ability to parse JWTs, or be able
to call node.js directly (not using a web service, etc... nothing else
needing to be running). If you can already, I'd love to see how. There

is

so much functionality available with OSS (node.js being my favorite)

that I

wish I could call it similar to calling Java or even just calling a CL or
RPG program.

Maybe that would be more suited for SQL (JWT processing that is)?

Naïve, hardly, you raise a good point.

As to your first question, I think you answered it yourself. The

compiler

merely turns RPG into executable code. I don't believe there is a

classic

"runtime" involved, since ultimately it winds up being some fashion of

MI

before the executable is created. Therefore the complier has to come up
with a way to build efficient MI code to execute the instructions.

Hence

only patching the complier. Furthermore if IBM wanted to patch more

than

the compiler in one PTF they certainly can do that. (and sometimes

do...)

Yes, this has been done many, many times in the past going back several
versions if not releases.

7.3
ILE RPG runtime: SI76098 - you need this PTF on any 7.3 system where
you run a program with %LOWER, %UPPER, or %SPLIT ILE RPG compiler:
SI76100

Interesting. So you need to patch the runtime as well. Is this normal?
I don't recall other language updates mentioning runtime PTFs, only
compiler
PTFs.

Notably, the RPG Cafe entry for the FOR-EACH, IN, %LIST, and %RANGE

bundle

doesn't mention any runtime PTFs:

https://www.ibm.com/support/pages/node/6342821 <

https://www.ibm.com/support/pages/node/6342821>

Those strike me as more substantive changes. If anything, I would have
expected those to require an updated runtime. %LOWER, %UPPER, and %SPLIT
seem like functions that a competent and motivated RPG programmer could
implement themselves, and many *have* implemented their own DIY

versions.

Granted, the DIY ones are almost always vastly more rudimentary than

these

BIFs (for example, a lot of native-English shops wouldn't bother to

handle

accented characters). But conceptually, these still seem very achievable
with the preexisting runtime. Is it naive of me to think that?
