Save and Recall

[schifferjack]

Hello, I'm currently working on a program that calculates the center of gravity of an aircraft and the program must be able to save the successful calculations which means lets say the output says "the aircraft is safe to fly" by using that output it will save the calculations that got the output in the first place for future uses. which means even if terminate the program and open it again, i can view the history of my successful calculations.
