Some BASIC programs (especially those using MODE 7 for teletext graphics) use an expression like
(USR &FFF4 AND &FF00) DIV 256
to read the character on the screen under the cursor. This is equivalent to
ASC(GET$(POS, VPOS))
Could this (and maybe a few other frequently used OSBYTE calls) be implemented? BBC Basic for DOS and BBC Basic for SDL do implement this functionality.
