模拟操作系统的主存分配，运用可变分区的存储管理算法设计主存分配和回收程序，并不实际启动装入作业。采用最先适应法、最佳适应法、最坏适应法分配主存空间。

-Simulation of the operating system main memory allocation, the use of variable storage management algorithm partition of main memory allocation and recovery procedures, and does not actually start the load operation. Using the first to adapt the method, the best fit, worst to adapt the method to allocate the main memory space.
