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

Are you a member of the Ryver OSS group Brad? There's always discussion on these points there. There are a couple of options already including Richard Shoen's recent offering but for sure more/better is needed. Sadly 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 river you'll get a better feel for it.

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?
