Re: Ti-86 wierdness
Yeah, that's exactly what I thought. Here's what this guy e-mailed me:
About 86's sending programs to 85's... TI did _not_ intend for programs
to be sent this way. Think of all the extra commands that an 86 has that
an 85 doesn't! Attempting to execute these commands on an 85 would
probably lock up the calculator.
I told him syntax error or undefined variable error is the only thing that
would happen. He replied:
However, you are incorrect in
assuming that it wouldn't lock up; if incorrect TI-BASIC is executed it
can very well lock up the calculator (I've done it by changing a single
byte in a program)
I figured he was full of it, but it's fun knowing that you've proved me
right.
