Code no longer working

[yk303]

As I said before, interspersing function definitions with other code will make it harder to follow the execution.

Line 46 is inside the function read_history(), so the variable assigned there is local to the function. It is not accessible outside the function. So when line 55 attempts to reference it, there is an error.

I don't know how to fix this. sorry. Should I break read_history() function.
