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}

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.

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}

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
