外國人寫的一個class,這么一點小小的應用,除非有特殊需求,還沒有必要模塊化。
用asp產生一個隨機數。

'' CLASS: cRandom
'' Calls randomize to seed the random number generator.
'' Provides functions for returning ranged random integers or arrays of

'' Calling randomize to seed the random number generator at the time the

'' This is a loop counter, set it to 0
