Massive program management method and massive program construction method

The invention discloses a massive program management method and a massive program construction method. The massive program management method comprises the following steps: dividing codes of a program into a plurality of code sections according to functions; packaging each code section into a function; naming the packaged function according to the function of the corresponding code section; storing the function into a library capable of being called by the program; and reprogramming the program into a library function calling program based on an operation sequence of the code. According to the massive program management method and the massive program construction method, the program code can be divided to realize functionalization; the modification and debugging of the program can be carried out based on the function so that the program can be conveniently managed and maintained; the methods are particularly suitable for large-size programs of the massive program codes.
