They should be operational : for many years to come. And while they are, their flight software will : be maintained here on the ground by JOVIAL (and hopefully jovial) : software engineers. There is also JOVIAL software in the F-16 and contemporary weapon systems, and it is still being maintained. However, every year, there is pressure to convert more and more of it to another language. Tools to support conversion of JOVIAL to other languages appear to be selling fairly well. I would be very skeptical if there's a single new project being written in JOVIAL, and I would guess all the existing systems will be gone within 20 years -- a relatively short lifetime compared to some MIS applications. I also suspect that the Y2K scare may have also put a significant dent in the existence of languages like RPG and JCL, but I could be wrong.
