Two questions - Cross Referencing (Automated label generation + Random items)
As I mentioned earlier, I am trying to use Context to make a multiple choice test. I have two questions. (1) Suppose I want to get a list of answers to the the multiple choice questions. One way I can think of doing this is by assigning a label to the CORRECT answer as done in the following code and then referring to that label. Is there a way these labels can be generated automatically, instead of hardcoding them as I have done below? defineenumeration[problem][text= ,location=inleft] \setupenumerations[problem][stopper=)] \defineitemgroup[choices][levels=1] \setupitemgroup[choices][1][a,packed] \nextrandom \starttext \problem This is the first question. \startchoices \startitem This is incorrect answer 1. \stopitem \startitem This is a wrong answer too. \stopitem \startitem[1] This is the CORRECT answer. \stopitem \startitem Yet another wrong answer. \stopitem \stopchoices \problem This is the second question. \startchoices \startitem[2] This is the CORRECT answer. \stopitem \startitem This is a wrong answer too. \stopitem \startitem This is not a correct choice. \stopitem \startitem Yet another wrong answer. \stopitem \stopchoices Answers to the questions \in[1] \in[2] \stoptext (2) When I add the option "random" to the itemgroup (\setupitemgroup[choices][1][a,packed,random]) then as expected the choices are listed in a random order. However, the label does not change with the choice listing. I want the reference to be attached to the CORRECT answer, which changes its position with random option. Is there a way to have the reference reflect the letter corresponding to the correct answer. Thanks in advance for your help. I really appreciate it.

You don't need \nextrandom any longer, it's fixed with the last beta. \newcounter\choicecounter \define[1]\Rightitem {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem} \define[1]\Wrongitem {\startitem#1\stopitem} \processbetween{rightitem}\Rightitem \processbetween{wrongitem}\Wrongitem
\starttext
\problem This is the first question. \startchoices \startitem This is incorrect answer 1. \stopitem \startitem This is a wrong answer too. \stopitem \startitem[1] This is the CORRECT answer. \stopitem \startitem Yet another wrong answer. \stopitem
\startrightitem This is the CORRECT answer. \stoprightitem \startwrongitem Yet another wrong answer. \stopwrongitem
\stopchoices
\problem This is the second question. \startchoices \startitem[2] This is the CORRECT answer. \stopitem \startitem This is a wrong answer too. \stopitem \startitem This is not a correct choice. \stopitem \startitem Yet another wrong answer. \stopitem \stopchoices

The labels change but they're always one run behind the current order. You can use a fixed random order for the items (the don't change after each new run) with '\setupsystem[random=3456]', you can change the order when you user another number. Wolfgang

\newcounter\choicecounter
\define[1]\Rightitem {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem}
\define[1]\Wrongitem {\startitem#1\stopitem}
\processbetween{rightitem}\Rightitem \processbetween{wrongitem}\Wrongitem
\startrightitem This is the CORRECT answer. \stoprightitem \startwrongitem Yet another wrong answer. \stopwrongitem

Awesome solution. Works great. Thanks very much Wolfgang. I can now use your solution. If it is not too difficult to explain, I would appreciate if someone could explain why the following does not work. It is not necessary because Wolfgang's solution is great but will help me understand it better. \def\AnsT {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem} \def\eAns{\stopitem} With these commands if I use \AnsT This is the CORRECT answer. \eAns \startwrongitem Yet another wrong answer. \stopwrongitem I get the error "File ended while scanning use of \startitem"

It has to do with the that for randomized items ConTeXt has to know the text for each item, to do this the normal \item ... is not enough and \startitem ... \stopitem is needed. Each \startitem ... \stopitem pair collects the text between it and add it to a list. The collecting works in the way that \startitem grab everything untill it sees a \stopitem command. If you want to write your own command you need a similiar mechanism where your \AnsT grab everything till \eAns but this did not work in the way you defined the command yourself. The low level way to do this is: \def\AnsT#1\eAns {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem} Another way to do this with a few ConTeXt commands is: \define[1]\Rightitem {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem} \define\AnsT {\grabuntil{eAns}\Rightitem} Wolfgang
The low level way to do this is:
\def\AnsT#1\eAns {\doglobal\increment\choicecounter \startitem[\choicecounter]#1\stopitem}
Wolfgang
Beautiful! Thanks again Wolfgang. I tried the low level command and it works great. I will try the Context way later. Hans, thanks very much for bringing to my attention the file m-educat.tex. Can you please tell me where I can find it? Even if I do not use it as it is, I am sure I can learn something and it can give me some ideas.

Dear Curious Learn (strange name, it can be considered rude not to use the real one) You can find m-educat.tex at tex/texmf-context/tex/context/base/m-educat.tex if you use the minimals It is also listed at http://wiki.contextgarden.net/Modules if you dont have that installation. Best regards, Mikael Persson
Dear Sirs Is there a way to include in Context documents some chemistry equipment pictures generated by the pst-labo package. http://www.tug.org/texlive/Contents/live/texmf-dist/doc/generic/pst- labo/pst-labo-docEN.pdf thanks for your support Jorge

Yes it is, you can use the 'pstric' module to create pictures with pstricks but it needs a few modifications. Give us a complete example from a picture you want to create, it's also important which TeX distribution you use, TeX Live or minimals. PS. Don't start a new thread with a reply to a older one, it will get lost in the old one and is hard to find and reduce your chances to get a answer. Wolfgang

Thanks for the information Mikael. I am sorry if my use of a non real name offended anyone. It seems to be the standard practice on many forums (I agree not on this one) and I stuck to it. Feel just more comfortable this way. Again, I apologize if it offended anyone.

long ago we made interactive tests and such; some of the code was split of in m-educat.tex ; i'm not even sure if it works any longer ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
