I added a INT 5, A0=13 system routine that loads in screen memory, files directly from the SDCard so I can easily display saved screens. Also I added a command LSCRN "filename", address in Tiny Basic.
I added also a command XMOV in CPU/assembly that can move data to and from "extended memory" so now Lion can access more memory than the 64K ram (currently 128K). The "extended" memory can be used only for data not for programs.
-- 28/6/2019 XMOV commands and extended memory no longer exist, they were replaced by page memory and commands
