Re: Survey for AS/400 Developers (ISERIES) DB2/400

Another issue is the idea of upward compatibility & the desire to continue 
using stuff that works fine ... if it aint broke why fix it ... well a new OS 
upgrade can break it.
We write software & it works.
We add views to solve perfomance problems & in association with modifications 
to add new features & it works.
We have some software package that is 99% written in some collection of 
languages & features ... it makes sense to remain expert in that collection.
We upgrade to a new OS & we lose IBM support for some products that now only 
have minimal IBM customers or IBM thinks can make more money by going in 
different direction, so we convert to a non-IBM platform, or to new IBM 
offering, or remain on obsolete OS.
