Program Ring_Bell;
{***************************************************
* This program has a two fold benifit. First, is *
* to assist when running a time consuming batch *
* file and I might be somewhere else within *
* hearing range like in the next room, I would *
* know immediatly when it finishes. *
* Last, it gave me a chance to figure out how *
* load parameters from the command line even *
* thought it's nothing fancy. *
* *
* The parameter choises are as follows: *
* A = Alarm, a steady bell till a key is pressed. *
* W = Warning, a pause between each bell till a *
* key is pressed. *
* B = Bell, a single bell. *
* H = Help, gives something like this. *
* ex. A>BELL B *
* Only one space between the second L and the *
* parameter. *
* *
* Version 1.00 *
