1. PL/0 语言介绍 ●PL/0 程序设计语言是一个较简单的语言，它以赋值语句为基础，构造概念有顺序、条件和重复（循环）三种。PL/0 有子程序概念，包括过程定义（可以嵌套）与调用且有局部变量说明。PL/0语言编译程序采用以语法分析为核心、一遍扫描的编译方法。词法分析和代码生成作为独立的子程序供语法分析程序调用。语法分析的同时，提供了出错报告和出错恢复的功能。在源程序没有错误编译通过的情况下，调用类PCODE解释程序解释执行生成的类PCODE代码。 ●保留字(关键字)：所谓保留字是指在Pascal语言中具有特定的含义。标准Pascal语言中的保留字一共有35个，Turbo Pascal语言一共有51个。下面是Pascal语言的保留字：AND，ARRAY，BEGIN，CASE，CONST，DIV，DO，DOWNTO，ELSE，END，FILE，FOR，FUNTION，GOTO，IF，IN，LABEL，MOD，NIL，NOT，OF，OR，PACKED，PROCEDURE，PROGRAM，RECORD，REPEAT，SET，THEN，TO，TYPE，UNTIL，VAR，WHILE，WITH，EXPORTS，SHR，STRING，ASM，OBJECT，UNIT，CONSTRUCTOR，IMPLEMENTATION，DESTRUCTOR，USES，INHERITED，INLINE，INTERFACE，LIBRARY，XOR，SHL -err

This schematic and Gerber files of PCB that is used for GSM alarm system. This is industrial-grade system with many features like 1-wire (iButton) interface, additional interface for video camera (UART JPEG camera is used), SD card to store pictures from camera and send them by GSM to remote mobile phone. Can be used as a reference design for anyone who wants to make own GSM alarm system system based on SIM300C module from Simcom.-This is schematic and Gerber files of PCB that is used for GSM alarm system.
