clears the screen.
This permits computing of characters and also advanced functions such as cursor addressing. The argument should be 0 - 255. Arguments greater than 255 will give an argument error.
The argument 15 instructs HUNTER Basic to interpret the following two arguments as cursor co-ordinates x,y respectively. It must be noted that re-positioning the cursor in this manner will not cause the virtual screen window to be re-positioned over the relevant area of the virtual screen automatically. If automatic re-positioning is required then use LOCATE.
