I spotted this in my morning news perusal: "Digitization? The entire network runs on software known as Jovial, so old there are only six programmers in the country who know how to write it. And incredible as it seems, family minivans with NavStar have more sophisticated location guidance than some aircraft." from: http://www.msnbc.msn.com/id/20724859/ Well, make that seven. I remember JOVIAL (it's all caps BTW). Worked on an NWL (or maybe it was NSRDC) project in it. Anyone else? Cheers, Chuck
