Dear Wolfgang and Otared,

Thank you for the reply.

I have used \setupinteraction[state=start] and open with Adobe Reader already. 

\StartSteps worked well in \startitemize and \startcombination. For example,

\StartSteps
\startitemize
\item $T(n) =$ \FlushStep
\blank[5*big]
\item $T(n) =$ \FlushStep
\stopitemize
\StopSteps
...

\StartSteps
\placefigure[none][]{}
{\startcombination[3*1]
{\externalfigure[TriNo60][width=.3\makeupwidth]}{\FlushStep}
{\externalfigure[TriNo90][width=.3\makeupwidth]}{\FlushStep}
{\externalfigure[TriNoDbl][width=.3\makeupwidth]}{\FlushStep}
\stopcombination}
\startformula
T(n) = n(n+1) \over 2
\stopformula
\FlushStep
\StopSteps

But I couldn't make it work with lines of formulas. I think that it is not working with \NC, \NR structure.

I'll try t-rsteps and thank you for the file. It is another good way to make slides.

Thank you.

Best regards,

Dalyoung

That’s weird because it works for me with the example you sent.

\usemodule[pre-60] 

\setupinteraction[state=start]

\starttext 

\StartSteps 
\startformula\startalign 
\NC T(4) \NC = T(3) + 4          \NR\FlushStep
\NC      \NC= T(2) + 3 + 4       \NR\FlushStep 
\NC      \NC= T(1) + 2 + 3 + 4   \NR\FlushStep 
\NC      \NC= 1 + 2 + 3 + 4 = 10 \NR\FlushStep 
\stopalign\stopformula 
\StopSteps 

\stoptext

Wolfgang

Dear Jeong,

I tested again your example file with mkiv and got the correct result (see the attached file). As Wolfgang says in his answer, it is weird that the \FlushStep command doesn't work for you: are you using mkiv? I should add that in mkii, the part of your example with \startcombination does not work correctly.

Best regards: OK

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

Add \setupinteraction[state=start] to your document and open it with Adobe Reader.

Dear all,

I'd like to show the following formula line  by line in a presentation,
For example, 
\startformula\startalign
\NC T(4) \NC = T(3) + 4 \NR
\NC \NC= T(2) + 3 + 4 \NR
\NC \NC= T(1) + 2 + 3 + 4 \NR
\NC \NC= 1 + 2 + 3 + 4 = 10 \NR
\stopalign\stopformula


I tried to use \StartSteps and \StopSteps but not succeed.

\starttext
\usemodule[pre-60]

\StartSteps
\startformula\startalign
\NC T(4) \NC = T(3) + 4 \NR\FlushStep %(nor \FlushStep\NR)
\NC \NC= T(2) + 3 + 4 \NR\FlushStep
\NC \NC= T(1) + 2 + 3 + 4 \NR\FlushStep
\NC \NC= 1 + 2 + 3 + 4 = 10 \NR\FlushStep
\stopalign\stopformula
\StopSteps

\stoptext

Is there a way to do so?

Thank you.

Best regards,

Dalyoung
