| 摘 要： | 本文介绍了利用微机本身把有格式的ASCⅡ码的数据文件转换成二进制无格式数据文件的方法,利用这种方法可以把有格式读入数据文件改成无格式读入数据文件,这样可把数据文件读入时间缩短约16倍,同时也可以减少数据文件占的字节数,节省磁盘空间。

| Abstract: | The time it takes to read a data file into memory can be as long as several minutes when the formatted data file erected by the keyboard is large. This paper presents a method of converting a formatted data file into a binary unformatted file on the microcomputer itself. The time the microcomputer takes to read data into memory is thus cut short by 17 times. Besides, the data file itself is shortened, which means a saving of disk space. |
