[Info-ingres] Is anyone still using ABF 4GL?

"Legacy app" made me smile. At my previous workplace the dev team leader would bristle at the ABF apps being called that, saying that they were current, under active development and relied on by the business.
Every place I've worked used ABF (at the time, I can't say whether they still do). It's still in use where I am now, though only for 1 fairly small application.
ABF projects developed over many years can be large and difficult to break down into more manageable chunks, should it be necessary to move functionality into something with a more modern look+feel. Back when I used ABF regularly I remember wishing that "call application" had options to pass globals around.
