Choosing programs

Publisher Summary The first step in choosing programs is to find out what is available. The most convenient way to do this is to study one of the several guides to computers in the construction industry that are available. Such guides normally give a brief description of the aims of each program, the machines on which it is available, and the name of the marketing organization. They are usually organized in such a manner that programs performing the same tasks are listed together. Thus the prospective user can see the choice in any application area. Additionally, browsing through these guides is a convenient way of finding out what scope the computer aids might have within an office. It is useful to get some idea of the amount of effort that went into producing the program. A large investment by the vendor at least indicates a willingness to take the trouble to get things right. Any program of less than 1000 lines of a high-level language is probably trivial. It simply does not have the space in which to make input easy for the user, solve a reasonably complex problem, and provide properly laid out results. It is wise to be particularly careful before buying a program emanating from a university or technical college. As they do not have to justify themselves commercially, the programs can be very good value for money. Even with a good program, it is important to check that maintenance and support is available all year round.
