Re: Classes for IBMi/iSeries?

[Trevor Perry <trevor@xxxxxxxxxx>]

Vern,

Did this not suffice: "PHP, Systems Director, RPG Open Access, RD Power,
and so on"?


This is such an open-ended question. Modernization is about leveraging
your existing business logic and moving forward to embrace new
functionality, integrate applications and enhance the user experience.
Keeping the same code you wrote on an AS/400 might be included in your
modernization roadmap, but writing code in 2011 like you did in 2000 is
probably not a modern exercise. Writing new green screen 5250 applications
is a little like asking your Windows users to run everything from the CMD
window.

Advocating change for change sake seems a little narrow minded, of course.
Backwards compatibility is not the issue, but not keeping up with the
platform, not keeping up with I.T. evolution, living in the glorious past
of AS/400 will prevent companies from moving forward. In the end, the
platform will be blamed, when it was the I.T. Department's fault, and
ignorant company management will throw it out.


Seriously, would ~you~ buy a ~new~ green screen application in 2011? Would
you buy an AS/400, or would you prefer IBM i running on Power?
