[Coco] Access to 225 lines in BASIC

[Nick Marentes]

I am creating a program in BASIC but I require the use of more vertical 
screen space than what BASIC allows.

Basic restricts all graphics (HSCREEN2) to a maximum of 192 vertical 
lines yet the display can be extended up to 255 (with a POKE).

The BASIC drawing commands restrict their drawing to 192 although they 
accept values up to 255 (I think) but truncate to 192.

Are there any magical POKEs to BASIC that allow it to draw up to the 
maximum?
