Programming Exercise 6, page 286

· Make sure that your code validates all input, displaying an informative message box for inappropriate input.

· You are to also do Challenge 2, displaying the results (type of card and credit limit) in the label at the bottom of the screen.

· You are to break your code down into smaller functions and subroutines, as you did in the previous assignment. At a minimum, you should have separate subroutines/functions for the following:

o Determining whether input is valid.

o Determining the limit and type of card (if any).

· Make sure that your code is well documented. In particular, make sure that it describes the purpose of each If statement, and what each branch represents.

· Make sure that you test your program thoroughly, coming up with at least one case for each possible branch.

· Save this project as Credit.frm and Credit.vbp. Make sure that your name is on the diskette!
