某正在运行的大型医院源程序，PB+SQLSERVER设计，对程序开发和设计非常有参考和借鉴作用，赶快下栽吧-are running a large hospital source, PB SQLSERVER design, procedures for the development and design of information and very useful, it quickly crashed

由系统随机建立一个迷宫,然后屏幕输出路径。为在完成作业的同时复习所学过的内容,完成一条路径的时候用到了递归的方法 而做全部路径的时候用非递归的方法。用户界面友好，有用户使用说明.每一步操作都有说明与提示。程序运行通过，有详细的解释说明-system by the establishment of a random maze, and then screen output path. For the complete review of operations at the same time have learned from the contents of a complete path of the use of recursive method to do all the time path of non- recursive method. User friendly interface, users note. Every step of the operation have notes and hints. Running through a detailed explanation of
