Actually this is more common that you'd think. Many cases the company didn't write the code, they contracted for it or it's a canned application. In most of those cases they never had the source! Then the people that had the source go out of business and the code is effectively lost. I worked for a company that had to sue to get the source for an app they used for some 5 years so they could fix a bug! The bug was that RSTS-11 upgrade cased the app to crash. They needed the upgrade to keep the hardware and OS service contract alive on an 11/34 that ran the place. Allison
