	Line 100 tells Business Rules! to jump to line 450. Unless a later (or earlier) statement in the program branches control to the lines between 100 and 450, any lines between 100 and 450 will never be executed. Note that line 450 must be present in your program before you can save it. Trying to use the SAVE or REPLACE command before you define line 450 will result in ERROR 213 (Line reference not found).

	Using symbols, we can visualize the progress of the MILEAGE program that you wrote in ~~the last chapter.~~		Using symbols, we can visualize the progress of the MILEAGE program that you wrote in [[Chapter 3]], where you also learned about the CONV error condition and saw how Zippy the Cursor jumped across several program lines to reach the error-handling routine for a conversion error. A program jump such as Zippy performed can be a very useful programming tool. It is usually referred to as a branching statement.

	1. Write a program to calculate distance in meters. The metric equivalent is that one meter is 39.37 inches. The user will input the distance in feet and inches (hint: use two separate INPUT statements for feet and inches). Allow the user to execute the program several times. The program should end when the user enters a negative number for feet (don’t forget to tell the user this arbitrary rule for how to end the program).		1.

	2. Write a program to compare two loans. Use a subroutine to calculate the amount of the monthly payment on a loan. You can modify the program that you wrote for Chapter 4, Assignment 2. For each loan, your program should accept a dollar amount, an interest rate, and a number of years. Your subroutine should do all calculations for the loan. A possible outline of your program is:		2.

If the user enters any numbers outside these ranges, the numbers should be rejected and a message should be printed about what values are acceptable (hint: use IF statements with AND or OR).

Modify the program you wrote for assignment 2 (or 3) so that the input section for the second loan will use corresponding values from the first loan if zero is entered.

	For instance, if the first loan is for $100,000, at 8 percent for 10 years, the user could compare the same loan at 9 percent by entering for the second loan 0, 9, 0 for the loan amount, rate and years, respectively. The program would treat this second loan as if the user had entered $100,000, 9 percent and 10 years.
