          Description
 
          SCROLLDOWN scrolls screen to the down so repetition will
          repeat the scroll number of times down, the string will only 
          display horizontally 32 characters of the string on right 
          side of screen. SCROLLDOWN puts the string on screen and 
          wraps to bottom if string is to long.
          If the string is empty (null) it will just scroll the screen. 
          Like PRINT TAB will go to next line right of left side of 
          screen each line till end of string. Numbers or varaibles 
          can be used instead of a string. SCROLLDOWN runs from ROM.
           Repetition can be 1 to 65535 max.
