Re: RPG II Conversion

[Brian Parkins <goodprophet.bp@xxxxxxxxx>]

I don't think you'll do any better than the approach you're already 
taking, Doug. I came across this suggestion back in 2015 from Scott Klement:

------------------------------------
Re: Moving from S/36 to modern RPG/ILE environment

You can, sort of, convert things from S/36 to modern times by doing:

a) Change the source type from RPG36 to RPG.
b) Try compiling... some S/36 features might not work.
c) Fix up the things that didn't work, repeat b & c until working. Now 
you have an RPG III program.
d) Run CVTRPGSRC to make it an RPG IV program.

The result, though, will still be using program-described files, 
six-character field names, and fixed-format code. It will be monolithic, 
not modular, not using ILE techniques, etc. To truly update the code 
isn't just a "conversion", it requires human intelligence to really do a 
good job of refactoring (and in many cases rewriting) the code into 
something modern. Tools from folks like Linoma and Arcad may help, but 
ultimately, it's not going to just be "convert and everything is 
modern". There's no way a computer can know, for example, the 10 (or 
more) character variable names to use when the old files had 6 character 
names that differed between each program...

HTH,
Brian.

PS. I don't know how useful this will be to you:
