A collection of related problem programs , identified in the input stream by a job statement followed by one or more exec and dd statements 相關(guān)的問題程序的集合。在輸入流中,由一個job語句后面跟一個或多個exec (執(zhí)行)和dd (數(shù)據(jù)定義)語句來標(biāo)識。
Par method can explain the whole process of " problem - program " as well as improve substantially the programming skills of students ; about the implement technology , the popular generic paradigm is incorporated and the results in ai ( knowledge representation and automated reasoning ) are used , which enables the system to be a truly " open system " with infinitely many problems and solutions , instead of just a compilation of fixed ones ; about the function of the system , it incarnates the constructivism and it has excellent human - machine interface , concurrence , and openness Par方法可以說清“問題程序”的全過程,可以解決現(xiàn)有程序設(shè)計教學(xué)存在的根本問題,幫助學(xué)習(xí)者實質(zhì)性地提高程序設(shè)計的能力;在實現(xiàn)技術(shù)方面,借鑒了當(dāng)代流行的泛型思想,并將人工智能在知識表示、自動推理等研究中形成的思想方法和成果應(yīng)用于程序設(shè)計icai系統(tǒng)的開發(fā),使得系統(tǒng)具有一個既有問題又有解答的無限題庫,這些解答是由自動推理產(chǎn)生的而不再是固定問題、答案的堆砌;在系統(tǒng)功能方面,充分體現(xiàn)了建構(gòu)主義思想,具有良好的人機(jī)交互性、并發(fā)性和開放性。
