Re: A85: x-stat and delete protection
That won't work. It's not an area of memory that's special, but the
varibales are. Ans, xStat, yStat, #, and ! all have special status on the
85. They cannot be deleted. # and ! are invisible, too.
If you play with a shell backup, you can delete the shell. It's located as
the very first variable in the RAM.
