Programming notation in systems design

In any area of systems design, the programming notation or language plays a key role. The programming notation or language used in the description of a system must fulfill several requirements: it must be universal enough to conveniently describe programs appropriate to each of the elements embraced in a system; must be precise; and be further concise and subject to formal manipulation. As an illustration, a programming language developed for, and already applied in, a variety of areas is presented.
