What is a better way to do this macro?

Dear gang,

Consider the following (also attached):

=====choice-cs.tex====
\def\CHOICE#1#2{\leavevmode\vbox{\tabskip=0pt\everycr={}
                 \halign{\strut\hfil##\hfil\cr#1\cr#2\cr}}}

\setuppagenumber[state=stop]
\setupwhitespace[big]

\starttext
(One~* Two~* Three~* Four) is even.

(\CHOICE{x}{One}~* \CHOICE{1}{Two}~* \CHOICE{x}{Three}~* \CHOICE{2}{Four})  
is even.
\stoptext
======================

What is best way to define the \CHOICE macro without low-level TeX  
commands, only high-level ConTeXt commands? Thanks in advance and

Best wishes
Idris

You can use the \framed command.

\define[2]\ChoiceOne
   
{\dontleavehmode\framed[frame=off,location=bottom,align=middle,offset=0pt]{#1\\#2}}

\defineframed[ChoiceTwo][frame=off,location=bottom,align=middle,offset=0pt]

\starttext

(\ChoiceOne{x}{One}~* \ChoiceOne{1}{Two}~* \ChoiceOne{x}{Three}~* 
\ChoiceOne{2}{Four}) is even.

(\ChoiceTwo{x\\One}~* \ChoiceTwo{1\\Two}~* \ChoiceTwo{x\\Three}~* 
\ChoiceTwo{2\\Four}) is even.

\stoptext

Both examples are very instructive!! Thanks a million, Wolfgang, and

Hi Wolfgang, all,

Here is a new test file. Objective: To control the interlinespacing of the  
\\ command inside of \framed while keeping the bottom argument y of {x\\y}  
on the same baseline as the rest of the sentence. Look carefully at the  
examples in the attached pdf and see how the baselines moves when top is  
used to control \\.

A mixture of the parameters top and bottom does the trick, but the use of  
bottom is an ugly hack. Is there a better way? See below and attached

Best wishes
Idris

=====choice-cs-new2.tex=====
\setupinterlinespace[line=1.8em]
\setupwhitespace[big]

\defineframed[Choice][frame=off,location=bottom,align=middle,offset=0pt]

\defineframed[ChoiceTop][frame=off,location=bottom,align=middle,offset=0pt,top={\setupinterlinespace[line=1.2em]}]

\defineframed[ChoiceTopBottom][frame=off,location=bottom,align=middle,offset=0pt,top={\setupinterlinespace[line=1.2em]},bottom={\vskip.14em}]

  \starttext

(One~* Two~* Three~* Four) is even.

(\Choice{x\\One}~* \Choice{1\\Two}~* \Choice{x\\Three}~* \Choice{2\\Four})  
is even.

(\ChoiceTop{x\\One}~* \ChoiceTop{1\\Two}~* \ChoiceTop{x\\Three}~*  
\ChoiceTop{2\\Four}) is even.

(\ChoiceTopBottom{x\\One}~* \ChoiceTopBottom{1\\Two}~*  
\ChoiceTopBottom{x\\Three}~* \ChoiceTopBottom{2\\Four}) is even.

Use the foregroundstyle key to change the interlinespace.

Works like a charm. Question: Should the wiki page be edited:

http://wiki.contextgarden.net/Command/setupframed

It has the equivalent of

foregroundstyle = <name>

Shouldn't that be changed to

foregroundstyle = <command>

Originally I looked for keys mapped to <command> so I tried bottom and top  
because and those are the only keys that are mapped to <command> in the  
description. Or am I missing something here?

Thanks, Wolfgang and

Best wishes
Idris

The foregroundstyle should list the same arguments as the style key from 
other commands/environments.

For a example look at the arguments for \setupdescriptions:

Ah! Perhaps disambiguating would help unsuspecting users. So in  
\setupdescriptions we have things like

style = normal bold slanted boldslanted type cap small... command
[i.e. style = <name>|<command>]
color = <name>
before = <command>

So in the explanation of the foregroundstyle key we could have, e.g.

foregroundstyle	= <name|command>

making it clear that this key takes both a name and a command argument.  
Anyway, thanks kindly and

Best wishes
Idris
