			Mause.exe,  Version 1.06
```
```
			Mouse enabled pAUSE command
```
```
 
```

			Usage:    Mause.exe  [ prompt ]  [ /T:seconds ]  [ /N ]

```
 
```

			Where:    prompt      is the prompt to be displayed (default: "Press any key

			                      or mouse button or wheel to continue . . ."; use "" to

			                      show no prompt)

			          /N          do Not flush the keyboard buffer

			                      (default: flush keyboard buffer when program is started)

			          /T:seconds  timeout in seconds (1..3600; default: wait forever)

```
 
```

			Notes:    Return code 1 for key, 2 for mouse, 3 for timeout or -1 for errors.

			          While Mause is running, the console's Quick-Edit mode will be

			          temporarily disabled; before exiting, the console's initial

			          Quick-Edit state will be restored.
