Some PDP 11 application packages are designed to give users with little com- - puter familiarity the tools to perform specific tasks. The DECWORD/DP word processing package, ES40 SCSI SCA Case 4Slot 11 electronic mail, and the ES40 SCSI SCA Case 4Slot 11 - - query and report system are examples of such specialized packages. Other application products are designed for professional programmers to create new software for a much wider range of tasks. Programming languages and packages such as ES40 SCSI SCA Case 4Slot 11 and the Professional Host Tool Kit fall into this category. - Programming languages have typically developed in response to specific func- tional needs. Some languages, such as ES40 SCSI SCA Case 4Slot, were originally intended for processing enormous amounts of numerical data through complicated formulas at high speeds. Others, such as ES40 SCSI SCA Case 4Slot and ES40 SCSI SCA Case 4Slot, were developed for com- mercial applications in which data management played a major role. And still others, like ES40 SCSI SCA Case 4Slot, were invented for use by students who were unfamiliar with computers and needed a simple, easy-to-learn language related to every- day speech. While some of these distinctions have become blurred over time, it is still true that certain kinds of problems are best approached through specific languages. The descriptions in this section attempt to show the special strengths of each Digital-supplied language in satisfying specific application needs. With an appropriate selection of languages and applications packages, the ES40 SCSI SCA Case 4Slot 11 system can satisfy the computer needs of users of multiple levels of - expertise and function.
