Hello,

I've noticed that \startitemize[random] does not mix the items randomly. Is it a bug or am I doing something wrong?

A simple \item is not enough, you need a \startitem ... \stopitem pair. Please add a note to the wiki.

\startitemize[a,random] \startitem A \stopitem \startitem B \stopitem \startitem C \stopitem \stopitemize

Thanks for a speedy response! I've also noticed a strange thing: the first item always is the first - it won't get mixed with the others.

This is normal although I have here a document [1] where the first item always appear between the other items,

There is a bug somewhere in the initialization of the random number generator. The first random number is always 1. An easy work around is to add \nextrandom somewhere before \starttext and then the first item will be random. Aditya

I was not aware of this cool feature in Context. This could be very useful in making multiple choice tests. I have one question. Is there a simple way in which one can switch between itemized lists that are random and non-random? For example, if I have 40 multiple choice questions, each of which has the following form:

Question Text \startitemize[random] \startitem first item \stopitem \startitem second item \stopitem \startitem third item \stopitem \startitem fourth item \stopitem \stopitemize

If I want the PDF file that has the items in the order I entered them in (i.e., not a random permutation); is it possible to do that in a way other than going and taking out the "random" from each itemize environment?

Use modes: \defineitemgroup[choices] \startmode[random] \setupitemgroup[choices][1][random] \nextrandom % to get rid of the randomize bug \stopmode \starttext \startchoices[n] \startitem 1 \stopitem \startitem 2 \stopitem \startitem 3 \stopitem \startitem 4 \stopitem \startitem 5 \stopitem \stopchoices \stoptext Compile this file with "texexec --mode=random " to get random choices, compile without --mode=... to get normal behaviour. If you want random all the time and normal a few times, then change \startmode[random]...\stopmode to \stopnotmode[nonrandom] .... \stopnotmode. Then when you compile with texexec --mode=nonrandom you will not get random choices, if you compile without --mode=... you will get random answers. Aditya

For multiple choice you can try: http://fourier.math.uoc.gr/~mk/much/example/ see: [NTG-context] create and grade multiple choice exams with MUCH an ConTeXT have a nice day Em 27/02/2009, às 10:45, Curious Learn escreveu:

The best would be to add

\appendtoks\nextrandom\to\everystarttext

to the core.

i'd rather try to figure out why the initialization fails; i noticed it a while ago, but couldn't find the reason ----------------------------------------------------------------- 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 -----------------------------------------------------------------
