Converting an old green screen application to run in a website is as easy as typing an email or uploading a photo to facebook. If you are an IBM i Software developer then the only change to the RPG code is addition of a single line below the WORKSTN definition in the 'F' Specs: using the HANDLER keyword.

I frequently hear the same message from the green-screen programmers "if its not broke -- don't fix it".
