Selecting a range of values

[mjlongo]

Hello, I have a job where the customer supplies 5 fields. F1, F2, F3, F4 and F5. They will either contain a zero or they will contain a numeric value. I have to select the range from the fields and print that range of fields when they are not zero. Fields inside the range can contain a zero. So for example:

F1=50, F2=100, F3=200, F4=300, F5=100: I print all fields.
F1=0, F2=100, F3=200, F4=300, F5=100: I print fields F2 through F5.
F1=50, F2=100, F3=0, F4=300, F5=0: I print fields F1 through F4.
F1=0, F2=0, F3=200, F4=0, F5=100: I print fields F3 through F5.
F1=0, F2=0, F3=200, F4=0, F5=0: I print only field F3.

I'm pretty sure I can come up with a long list of if statements to handle this but I'm also sure there is a smarter way. Maybe using some kind of test on an array? Any ideas on how to handle this would be greatly appreciated.
Thanks!
