Re: NT vs AS/400

Hi Nathan,

Your points are valid, and I tend to agree with most of what you've written.
I wasn't really trying to single out RPG in my observation. It's just that
the language is so predominant on the AS/400, that it seemed natural to
correlate demand for RPG programmers to demand for AS/400 servers. Rest
assured that I'm not trying to start an RPG .vs. SomeOtherLanguage thread!

This whole discussion has been interesting. I learned some things that I
didn't know, and discovered a few different ideas that I need to explore
further. It's too bad that we weren't able to get any of the IBMr's involved
though. I'll bet they must just sit back and shake their heads when they
read some of the things that we come up with. :)

It was a good exchange. Thanks for sharing your thoughts.
