Hi Jeong,
If you are interested in using the commands defined in the old t-rsteps.tex for
showing formulas or text step by step, below is an example I use (it works with
mkii and mkiv). The input file I use can be found here
http://dl.dropbox.com/u/4316076/t-rsteps-ok.tex
but I attach it also to this message.
The old « raw steps » is handy when one may need to go backward in the steps or
when you want to show, say, the third line of your formula before the second
line, but it has the disadvantage of creating one page per step.
\starttext
\setuppapersize[S6][S6]
\setuppagenumbering[state=stop]
\input t-rsteps-ok.tex
\setupinteraction[state=start]
% uncomment the following when not needing teps
% \UseStepsfalse
% when using \UseStepstrue, we redefine \placeformula...
\ifx\UseStepstrue{\def\placeformula[#1]{\PlaceFormula[#1]}}\fi
\StartSteps[Formula with steps]
\startformula
\startalign
\Step{1}{\NC T(4) \NC = T(3) + 4 \NR}
\Step{2}{\NC \NC= T(2) + 3 + 4 \NR}
\Step{3}{\NC \NC= T(1) + 2 + 3 + 4 \NR}
\Step{4}{\NC \NC= 1 + 2 + 3 + 4 = 10 \NR}
\stopalign
\stopformula
\StopSteps
\stoptext
Best regards: OK
