instead of trying to explain all the different conditions I've tried, maybe there's a much simpler approach to the following situation:
I want to be able to input a unknown number of values, ending the list with the value 999
I then want it to take the difference of each consecutive value.
Finally, output these differences in a list.
I do not want the outputs list mixed in the inputs list... I want all the inputs listed first (as they're entered - an unknown number of inputs), the list ending with 999.
Followed by a list of outputs...
p.s. the equations and code is simple enough, just the formatting of getting all the inputs first then listing all the outputs is where I'm stuck.
