刚开始设计时对PL/0了解并不多,随着设计的开展,对PL/0也有了一定的认识,了解了其主要思想.在自己动手的同时也学到了许多课本上学不到的东西.几天下来,我完成了对一些符号,-=,+=运算和FOR语句的扩充,并完成了--,++运算功能的扩充.-The beginning of the design of PL/0 does not know more than that with the launching of the design of PL/0 is also a certain awareness, understanding of its main ideas. In their own hands at the same time learned a lot less than what school textbooks . a few days, I completed a number of symbols,-=,+ = operator and the expansion of FOR statement, and completed-,++ computing function expansion.
