本程序设计用于模拟实现包括FCFS、SSTF、电梯、scan算法在内的磁盘调度算法，计算出各种算法的磁头移动道数供用户参考比较。-This program is designed for analog realization, including FCFS, SSTF, the elevator, scan the disk scheduling algorithms, including, heads of various algorithms to calculate the number

界面响应,用IDL开发的。如果用户在draw区域进行鼠标的左击、右击，键盘，以及滚轮的移动等操作，就会将这些全部显示在text内。-it is done by IDL.if one operate on the screen,it can write down what you have done.
