   > Or not scrolling I guess. I want to fill a the text screen with a character,   
   in assembly. I'm using COUT, but the last character will cause the screen to   
   scroll up one line and leave a line blank at the bottom. Is there a good way   
   to prevent this    
   beside printing everything but the last character and then directly sticking   
   the last character into screen memory?   
      
   The simplest way I have seen so far is to increase the vertical and horizontal   
   window sizes.   
      
   Increase $21 by 1 and $23 by 1 of zero page, set your htab and vtab then print   
   your character to the bottom right hand corner using COUT.  And reset $21 and   
   $23 back to normal.   
      
   Try this:   
      
   0300:A9 17 20 5B FB A9 27 85   
   0308:24 E6 21 E6 23 A9 C1 20   
   0310:ED FD C6 23 C6 21 A9 14   
   0318:20 5B FB 4C 8E FD 00 00
