Re: [racket-users] Newb question....About "How to Design Programs" book
First, I strongly recommend the second edition, which is what you get at htdp.org. In that case, you'll do many things differently with respect to teachpacks, but the ideas will be very similar. Second, when you choose "Add Teachpack" from the "Language" menu in DrRacket, you should see three panes. The left one, labeled "HtDP" is what you want for the edition you've been using, and indeed you want to choose "convert.rkt". After you add that teachpack, when you next hit "Run" the top of the interactions window should list the installed teachpacks, with a line like: "Teachpack: convert.rkt" Do you see that?

Re: [racket-users] Newb question....About "How to Design Programs" book
Thank you, Sam- I'm apparently reading a pdf version published in 2002 (Copyright 2001 Third Printing). Of course, it still refers to DrScheme and Scheme. Is there a newer one? I'm at Exercise 2.2.1, converting Fahrenheit to Celsius. The exercise calls for installing the teachpack "convert.ss" but that isn't in the list of teachpacks I see listed in DrRacket. I tried to install convert.rkt, but I have no idea if it actually installed or not because I didn't get any feedback telling me it was successful. I presumed that I should use the "Beginner" student version of Racket, but that isn't clear either. So, when I go to run my routine I get a "function is not defined" error, and I'm a little confused about what I missed. Huh! I just checked my version against the online version, and they are NOT the same! I prefer reading PDFs on my Android tablet, but I think I will need to see what happens when I follow the web version.

Re: [racket-users] Newb question....About "How to Design Programs" book
Which edition of the book are you using? And can you point to where in the book you ran into trouble, and what happened? The full book is online, so a link to the section would be very helpful.

[racket-users] Newb question....About "How to Design Programs" book
I'm sure this has been asked and answered, but are their any current descriptions of how people are adjusting to the book, "How to Design Programs"? I ran into a problem on the first little exercise that required me to use a teachpack. Surely someone has a lit of work-around for this?
