what are the bad parts? My answer would be that you cant use it to write a
green screen program. If it could, shops would have a migration path away
from RPG.
- It isn't written to leverage or integrate intimately with any operating
system which is something I like a lot about RPG.
- Java requires a fair amount of ramp up time when developing a new
applications because I always end up "going shopping" to see if the tooling
I am using is still the best/easiest and usually find something "better" and
go with that (think about ORM, logging, UI, etc). "Going shopping" is
necessary to keep up with the Jones' so you can hire people to maintain what
you've built.
- It is syntactically wordy. One could argue this doesn't matter with
intellisense, but I still have to look at the code when I maintain it.
- Doesn't come with nice business minded "bifs" out of the box and instead
you are required to build your own which will then be different from shop to
shop (no standardization like RPG).
- Java on the native iSeries side isn't "single JVM" minded like an app
server. This equates to many JVM's being up and running at a given time
which can't be good for performance.
- No native DB access, and instead you have to go shopping for ORM de jour.
I love the idea of IBM competing and improving RPG.
Now if we could get them to do a GUI we could actually go to market and
compete with Microsoft on the "looks" front :-) Right now RPG and GUI are
in the same place as Java and it's tooling: you have to spin your own wool.
That makes RPG+GUI very laborious and different at every shop.

I think the language should be less like RPG and more in tune with Java.

threading and elimination of the RPG cycle is great news. Would like to
know
if RPG programs can now be called recursively. )
RPG has had recursion for more years than I have been with the platform.
Guessing it came in V3R1 when ILE came.
I just checked. I think you are right ;)
Java has good and bad parts.

Hopefully RPG will only ever take on the good
parts. Multi-thread safe holds some nice possibilities for scaling
client/server programming. Maybe we should build and starting coining the
term "RPG App Server" :-)
check out this video for a tiny sliver of what MSFT is doing on the language
front. It is about extensions being added to .NET languages which allow each
iteration of a for each loop to be run in parallel, on as many threads as
the hardware can run simultaneously. I love the idea of IBM competing and
improving RPG. They have to spend the investment money which matches the
competition.
