可变式分区分配思想建立存储分块表MBT，使用首次适应法为新作业寻找可用空间。

输入内存空间大小、MBT表长度，显示初始MBT表的状态，以后每分配一次空间或释放一次空间都要显示当前的MBT表。当选择“分配空间”操作，则需要输入新作业所需的空间；当选择“释放空间”操作，则需要输入想要释放的作业号。-variable thinking of establishing regional distribution storage block table MBT, use the first method to adapt to the new operations to find the available space. Importation of memory space size, the length of MBT table, table shows the initial state of MBT, every subsequent distribution of a space or a space must release shows the current MBT table. When choosing the "space allocation" operation, the need for the importation of new operational requirements for the space; When choosing the "release space" operation, will need to import want to release its operations.
