Isn t it true that the problem is mostly found in only legacy programs?
It is true that the problem is significant to old, fragile mainframe code used in businesses around the world. These applications have been around for a long time, and have been modified so many times (often undocumented) that they are now very difficult to change. However, the need to handle legacy data is the basis for almost all computer systems, including mainframes, mid-range systems, networked workstations (such as those on local area networks) and stand-alone personal computers. It affects operating systems and imported data.
