對任意給定的文法G 構(gòu)造LR(1) 項目集規(guī)范族，其中要實(shí)現(xiàn)CLOSURE(I)、GO(I,X)、FIRST 集合等。在此基礎(chǔ)上， 構(gòu)造了LR（1）分析表。然后對輸入的句子進(jìn)行語法分析，給出接受或出錯報告。 程序采用文件輸入輸出方式。其中包括兩個輸入文件：文法grammar.txt，以及 輸入串input.txt；兩個輸出文件：項目集items.txt 和文法的LR(1)分析表 action_table.txt。由于語法分析的結(jié)果只給出接受或錯誤報告，比較簡

This is the source for a C compiler that generates 386 or m68K code. Code generation is fairly good although the optimizer is a little naive... the code itself should be highly portable although there are some issues involved with porting from MSDOS that have to be resolved for example the size of LONG on unix machines is so big some of the code generated gets messed up. Code generation requires TASM to assemble the compiler output you can use the borland TLINK to produce executables, or the Watcom WLINK can also be used. PMODE systems written by TRAN are used for the DPMI interface.

Flash中內(nèi)置了一個狀態(tài)寄存器（Status Register，SR）來指示Flash的當(dāng)前工作狀態(tài)和各種操作是否成功。要讀取SR的當(dāng)前值需要向CUI發(fā)送讀狀態(tài)寄存器命令（Read Status Register），命令碼為0x70，SR中的內(nèi)容將在DQ[7:0]上輸出。The Read Status Register （0x70）command causes subsequent reads to output data from the SR until another command is issued. The SR bits are output on DQ[7:0].

This article introduces how to construct a Hospital Ward Information System with three-tiered technology. The System applies to UML, BDE, MIDAS, distributed compute theory and a special architecture to make such functions: patients check in and check out, prescription input, drug-delivery at center pharmacy and information of patient manage with computer networking.
