對PL0原編譯器進行了以下的擴充:1.增加以下保留字else(elsesym), for(forsym),to(tosym),downto(downtosym),return(returnsym),[(lmparen),](rmparen) 2.增加了以下的運算符:+=(eplus),-=(eminus),++(dplus),--(dminus) 取址運算符&(radsym),指向運算符@(padsym) 3.修改單詞:修改不等號#為<> 4.擴充語句:(1)增加了else子句 (2)增加了for語句 5.增加運算:(1).++運算 (2).--運算;(3).+=運算 (4).-=運算;(5).&取址運算; (6).@指向運算; 6.增加類型:(1).增加多維數組a[i1][i2][i3]……[i(n-1)][i(n-2)][in] (2).增加指針類型(任何變量都能存放指針,但不支持指針的指針,如b:=@@a應該改寫為c:=@a,b:=@c) 7.將過程procedure擴展為函數:(1).允許定義過程時在其后加參數(var a, var b,……..,var n) (2)允許通過指針向函數形式參數傳地址;(3)允許返回值;可以用 a:=p(a,b,c….,n) 返回

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity. The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions.However.there are many shortcomings in traditiona1 measurements.This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page.Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient.

The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively. The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

This document provides guidelines and describes how to easily port S60 2nd Edition C++ applications to S60 3rd Edition. The document has been written based on experiences of porting regular S60 2nd Edition applications, such as the S60 Platform: POP/IMAP Example [4] that can be downloaded from Forum Nokia. Code snippets from the example are shown in Chapter 8, “Application build changes,” and in Appendix A, “Code example." In addition, Appendix B, "Commonly used functions that require capabilities," and Appendix C, "Commonly used interfaces that have been changed or removed," provide useful information on some frequently used functions and interfaces in third-party applications.
