OSBYTE &DA (218) - Read/Write VDU Queue length

   Minus the number of bytes need to complete this VDU command are held in 
   this location. So a command expecting 2 more parameters would have 254 here.
   Setting this to zero would (for example) clear the queue, preventing an
   error message having its first few characters lost
