Hello, I am a chemical engineer and have used APL for my graduate thesis. I am really fascinated by APL and I am positively interested to use APL in the future. My question is: What are major "applications" of APL? * Applications refer to a more direct application in industry or an applied research. I am more confused about how does the power of APL gets reflected "GLOBALLY". In other words, I need some MACRO exposure of APL. Thanks to " Vipul Sagare Box C3883, Bucknell University Lewisburg, PA 17837 717 524 5752

Trading systems for large foreign exchange brokers. One such system allowed Morgan-Stanley Bank to not only stay on the air during Black Monday (when the competition was falling hours behind, giving traders old information to allow them to trade themselves into even deeper holes, or of the air entirely, due to things like counters overflowing due to trade volumes), but they made money that day. b. Large multi-user systems such as a 1200 concurrent user email system. (Email systems have been around in APL since at least 1971, and perhaps longer. They tend to provide a level of flexibility and security which most of today's email systems still cannot achieve). c. Inventory and scheduling systems for large manufacturing companies. Xerox is probably a good example of such a firm. d. Computational chemistry for the petrochemical folks and for pharmaceutical companies. e. Very Large Data Base distribution. One such collection of systems cranks data out of many hundreds of gigabytes of data to many hundreds of concurrent users. APL provides a level of flexibility and rapid development allowing them to respond to changes in client needs, changes in data base feed formats, performance requirements, etc., in a way that is not possible with traditional languages. I know of one site which has been trying to kill off APL data bases for several years now. The story I heard was that by the time they get the C or SQL or whatever code working, the APL based system has changed enough due to client requirements that they have to start over. It's been several years now, and they have spent a LOT of money, and converted zero data bases. Other netters can probably add good examples from other areas. IBM uses APL a lot for internal work, which you can see if you read the IBM Journal of Research and Development, and note the fine print on implementation languages. Bob
