Re: Open Source RPG ? -- MIDRANGE-L

David, Pat,

I think that open-sourcing RPG would be a *horrible* idea. Itwould whither and die.

1) Not enough interest. RPG has been around for decades, yet it hasnot caught on much outside of the IBM midrange. Open source projectsfor the /400 have been very limited.

2) This is a compiler we're talking about, not an application,utility or tweakable framework. I suspect that that the pool ofqualified (and willing) candidates for this type of project is tiny.

3) RPG depends on many of the underlying system and database support,e.g. journalling, native I/O, data areas, spooling, etc., which don'texist reliably outside of the iSeries.


4) R&D moneys won't be there and people will not want to bet the farm on it.

5) Hooks into the OS (let's say for a full native GUI interface)still depend on IBM, so they will probably never make it into the OS.


6) IBM does compilers well.  Why grab it from them?

Very well said David. I have often wondered just exactly what
business in their right mind would actually use "open source"
for anything other than "just looking".

I'm sure this whole open source thing has some great value,
but to actually create a complete system written with a
language that "might" or "might not" have support sounds like
insanity to me.
