RE: VRPG And/Or Java

[Scott Johnson <sjohnson@xxxxxxxxxxxxx>]

John,

How about BOTH..   

If I am doing a GUI app I would use VA/RPG and then generate the Java
Byte Code if needed to run on something like Mac or Unix.  If I am going
to run the app under WIN95, I don't really need the Java stuff because
it can already run there just fine.

If I am doing a batch app I would use the Converter product.  Maybe make
this a part of IBM's CODE/400 product.  But, if I am writing a batch program
for the AS/400, I would compile it to 'native' for performance reasons.  Unless
IBM is going to work some magic and have Java performing the same or better
than the compiled RPG IV code..

--  Just my two cents worth!

VA/RPG And/Or Java

Hey Ya'll (or Use Guys)

If there was a discussion about VA/RPG(Visual RPG) and Java Which of the 
next two choices(or both)would people be in favor of.

1. VA/RPG being able to generate Java Byte Code.
2. A conversion product that would take RPG code and generate Java source.

Option 1 would allow you to generate GUI applications using the scripting
language you might have been using for 5,10,20 years. (Same old IFEQ, SETLL,
DOUEQ<g>, CHAIN, etc.).  The VA/RPG product BTW has a conversion tool that 
will take an existing (say) subfile program and convert it to a GUI PC app.
Option 1 would also allow you to generate object code(Java bytecode) which
would run anywhere Java will run,  from VA/RPG source.

Option 2 would be a CVTRPGSRC type thing that converts RPG(or VA/RPG to 
Java source.  With the idea that you will put a way your coding sheets
(what ever they are) for the { } world of Java.

How many would like to continue to use the scripting language you have been
using for years. Or switch to Java(C like as it is)?

If Option 2, Please make reference the plans concerning the inevitiable 
reality of having to have to still deal with 25,000 to 500,000 lines of 
existing RPG applications that you will still have to have the skill set
on staff to maintain. 

And also what language would you use for the typical batch(Monthend A/P,
G/L, etc. Not to mention Trigger programs, APPC programs, etc. that a 
visual language doesn't deal with to nicely) type functions? 

I'm very curious about your feelings on this.  (Give it some thought to 
my last couple of points.)

Sorry I was a way for a week and missed most of the below thread.
