I suspect that most software written 8, 10 or 15 years has long since outlived its usefulness. Example: At (an unnamed division of) ITT, I ran into a receiving system that constantly crashed, and when up was very, very slow. Often I would go down to receiving, checking on what was growing roots there and hadn't been shipped up to us (everything from disks to disk drives. What bozos!) On several occasions I was told the that "the terminal was full". It seems the DBMS could only hold a finite number of entries that was obviously to low. The DBMS? It was written 10 years ago and when contacted, the vendor was amazed to find anyone still using it. The source code? Not even the vendor had it around anymore. In this 'age' of new! and improved! software (SuperCalc --> Lotus 1-2-3 --> ??) I don't think maintaining the bridge between applications on microprocessor driven systems is as important as it once was (any may still be) with mainframes. Applications software simply changes too fast. -- David Hinnant SCI Systems, Inc. ...{decvax, akgua}!mcnc!rti-sel!scirtp!dfh
