Re: TIB: Invalid instruction?
Nope, the line(x1,y1,x2,y2,0) command really doesn't work. On the
TI-86 you can type in the letters for a command because they are
tokenized before running. The first time you run the prog after
editing, the calc turns the letters into tokens. On the 82, for
example, "line(" is a token already, that's why you can't type in the
commands.
