RE: RPG easier/harder to use than other languages?

Do you have some examples of how these former disgrunted OO devs have found OO programming to be flawed ?

Just curious since your statement seems pretty generic.

I'm seeing a number of disgruntled former OO devs these days claim that OO is flawed in concept. Personally I haven't done enough to have my own opinion. I have seen some crazy designs where people try to force a strict "text book" OO solution over problems where that concept doesn't really seem to fit.

Lots of business needs are better served by OLTP and relational database rather than OO. Sure, for the user interface OO is great, so use javascript in the browser and RPG in the server. Do not use 5250. Do not use "screen scrapers". Develop for web.

How do you classify a language as modern or not? The OO model is quite old. Java is showing its age to. Python is from the 80s.

Is OO the right tool for everything? Interpreted languages require very careful testing, and control over the input.

When there are lots of transactions, a compiled language like RPG or Cobol will enable the same processor to handle easily 20 times more transactions than the same code in PHP. Moore law does not work anymore, the speed has remained at 4 GH since the last 10 years or more. It is far more expensive to set up 20 servers rather than the difference of cost between developing in PHP or RPG.
