[Coco] Nitros9 and Set Status Call SS.AScrn

[Robert Gault]

Walter,

It might be easier to understand if you read the Tandy OS-9 Level II manual on pg. 8-142

Entry Conditions
  A=path number
  B= $8B
  X=screen type
    0= 640 x 192 x 2  colors 16K
    1= 320 x 192 x 4  colors 16K
    2= 160 x 192 x 16 colors 16K
    3= 640 x 192 x 4  colors 32K
    4= 320 x 192 x 16 colors 32K
Exit Conditions
  X= address space of screen
  Y= screen number (1-3)

As you can see, these are all PMODE type screens which is why they are handled by VDGINT. Also the 
screens are only allocated by SS.AScrn. You must use SS.DScrn to display the allocated screen. See 
pg. 8-143

Entry Conditions
  A=path number
  B=$8C
  Y=screen number (1-3 see above) or 0 which returns to a text screen
