Click on Files / Rick Wendel / Case Statement program. What am I doing wrong?

Hello rick, you completely forgot that you have to enter the operations
in Reverse Polish Notation (Don't worry I steel find myself doing that
mistake) and also you are missing one THEN and there is an extra END,
and the world "DEFAULT" should be right before the last end, so it
should be like this:

Line Number Program

1 << ¨ A

2 <<

3 CASE

4 A 5 <

5 THEN A 2 * END

6 A 10 <

7 THEN gTWOh END

8 A 15 <

9 THEN A 2/ END

10 "DEFAULT"

11 END

12 >>

13 >>

Thanks again.
I've got the IF-THEN-ELSE-END statements figured out and the CASE statements. Now I'm trying to get the IFTE command to work with RPN and get a few examples of START-NEXT loops. I have yet to figure that out. Check out my download files. It gives you access to about 63 different files.

I checked out your loops tutorial. It looks pretty good so far. I understand just about all of the basic programming structures now, well enough to start making some practice programs. Nancy VonEssen suggested a website at Thiel College. It looks like they actually have a calculus program there i.e. they know something about math. A found a wealth of information there. I have tons of information from them and I think it would help you out a lot.
