1、程序采用二级文件目录（即设置主目录MFD）和用户文件目录（UFD）。另外，为打开文件设置了运行文件目录（AFD）。
2、为了便于实现，对文件的读写作了简化，在执行读写命令时，只需改读写指针，并不进行实际的读写操作。
3、因系统小，文件目录的检索使用了简单的线性搜索。-1, the program uses two files directory (ie, set the home directory MFD) and user files directory (the UFD). In addition, in order to open the file set up to run the file directory (of AFD).
2 has been simplified in order to facilitate the achievement of the file read and write, read and write command, just change the read and write pointer, not the actual read and write operations.
3, because the system is small, the file directory search uses a simple linear search
