<HTML> <HEAD> <TITLE>Re: [plt-scheme] dr.scheme v207</TITLE> </HEAD> <BODY> Try instead going to the Language menu and choosing Add Teachpack, then selecting the teachpack you want. I'm not sure which book you are talking about, but you might also want to look at How to Design Programs, which can be accessed online at www.htdp.org. You don't need to run any code or use any teachpacks to learn from it! ;) (It may actually be almost the same thing you are trying to use, as HtDP and DrScheme are closely interrelated) Good luck with DrScheme! -Connor >>on 8/2/04 4:04 AM, canan ipek wrote: <BLOCKQUOTE>Hello, I am just starting to learn dr.scheme, but I cannot start the simply.scm code to follow the book and exercises. I loaded the "simply-teachpack.scm" to teachpack folder but whenever I try to execute the file I get the teachpack error message saying "not allowed in an expression context" I have no problems in executing other teachpacks in the teachpack folder. I will be very happy if you can help me solve this problem. thanks in advance Canan. </BLOCKQUOTE> </BODY> </HTML>
