3.1.5 variable functions

Conclusion:

16. Describe how you might modify the plus command so that it can reset a varialbe block to zero within a program.
The plus program has an option to use it as a reset block, allowing that block to reset all the blocks with the same value to a set value [0] when the program passes the function. Once they are reset, the program can restart on a loop indefinently.
17. What might an industrial or manufacturing engineering need to count or keep track of? Describe one example.
The number of products made is an important number in manufacturing, of course. Industrial machines always have counters to measure the amount of product being created, especially if it is something like jelly beans or marbles that come in packages of many products together that need to be specifically measured by weight and/or number.
