In some systems, it is desirable to allow the end user to answer some questions and quit mid-session, with the ability to return to the same session later. This can be very useful when the system:

• Asks many questions and takes a long time to run
• Asks a question that the end user may not be able to immediately answer
• Requires input from several different users, each providing answers to some questions
• Implements a "model" that can be run in a "What-if" mode, changing some of the input values

This demo will ask a few qustions. At any point you can click the"Save" button, which will save your data. You can then close your browser. When you run the system again, it will ask if you want to continue the previous run, recover your data and continue.

Another approach to the problem is to automatically save all user input after they answer each question. This allows them to just close the browser with no data lost. (Separate "How To" Documents explain how to implement this approach.)

When running the system, any input can be selected. There is no logic associated with the answers, the goal of the demo is only to show how the input can be saved.
