Re: framework question

Hi Joe,

first of all, procedural programming has no means of namespaces, its a 
nightmare to maintain.
Even with ILE and the concept of modules, its far not as readable as OO 
based code. But i dont
want to argue against ILE and its existance, i wrote too many years RPG 
myself . Also i dont
want to argue wether OOP in general is the way to go, because its 
obvious, i think we
discussed if you want to use  inheritance over composition. First of 
all, its not a black or white
type of question. It really depends.

If you have an Article which knows how to calculate itself generally, 
you can create a child of
Article, for instance Batharticle, you can easily override the 
calculation for that, reuse the
one the Article has or even mix both caculations. All this in a defined 
namespace resulting readable
code. In procedural languages, you mostly have function-collections with 
name clashes which call
each other quite wildly. To me, working with Inheritance or OO in 
general makes reading code much
easier, its more expressive.

If business programming can be achieved with Java? Look at all those big 
projects going on, most
banking applications are converted to java, ebay is on the way to be 
converted from procedural
stuff  to java. IBM is trying to move all its customers to java, so i 
think, business programming
is not so cumbersome at all. If you speak of quick hacking, OO is not 
the perfect choice, then
you are better of  with also not using ILE. Then RPG/400 is the way to 
go ;-) Or use one of these
sillly iSeries 4GL RAD Tools like Magic or the other one whose name i 
forgot.
