Form Letter 1 example:
Form Letter Assignment: You will change the code examples above so your javascript program will ask the user for 5 variables. One of your variables will be a number. After you click on the button, your program will use these 5 variables in a form letter. In addition, you will add or subtract (or any calculation) something from your number input and use this new variable in the letter, giving you a total of 6 variables. You will print out a listing of your program as well as a copy of 2 different runs of your program, and submit the papers to me before class on April 12. See me right away if you have questions. Remember to save different versions of your work and return to a running copy if things get broken. Good luck!
