Your exit is not really executed, because as you see, you are without 
some nesting (the 3 in 009:3> tells you you're in sine three things, 
like three classes or methods or something). You must first go out of 
all things you're in by typing end in each line (or closing brackets). 
Usually when you do a mistake, just type end and press enter until you 
see the prompt ends with NNN:0> again (there might be some error message 
too, just ignore it), and then your exit or anything else will work.

But for testing, just write a separate program! You won't have to repeat 
everything in case of a mistake every time. Here is something about 
writing separate programs:
