   CLS
   CLS [color]

The CLS command clears the screen, setting it (possibly) to a given background color. The clearing occurs with respect to the selected mode, so it will be a “pixel by pixel” clearing (if in bitmap mode) or “tile by tile” (if in tile mode). In the second case, the value of the EMPTYTILE variable will be used, possibly overridden.

  CLS WHITE
