As I am used to the TI-86, where you have to use right-back routines to
save any program information permanently, I was surprised and initially
confused when I found that programs run a second time retain information
variables from the first time.  Perhaps your program relies on a
variable being within a certain range or value at the start, and it is
modified when you run the program to completion.  Then when you start it
the second time, the variable is still the modified value, and causes a
crash?
