Abstract
PURPOSE:To improve the data compressing rate, by extracting the differences between stored 1st and 2nd data at every character and storing these differences. CONSTITUTION:An original source code A and a processing object source code B are stored in the source code files 1 and 2 respectively. A processing part 3 takes out each row of both codes A and B to obtain the differences among these rows at every character and extracts the changing position information on each character of the code B to the code A as well as the character information on said changing position to write these information into a compressed file 4. Thus the differences between 1st and 2nd data are extracted by a difference extracting means at every character. As a result, a high compressing rate is obtained.
