I use following in Latex to generate old factorial symbol:

\newcommand{\oldfact}[1]{% \tikz[baseline]{\node[anchor=base,inner sep=0.3ex](mynode){\ensuremath{#1}};\draw(mynode.north west)--(mynode.south west)--(mynode.south east);\path[use as bounding box]($(mynode.south west)+(-0.3ex,-0.3ex)$)rectangle($(mynode.north east)+(0.3ex,0.3ex)$);} }

What do you expect here to pass as argument to the oldfact command?

But I do not know how to make it work in ConTeXt as I am not very familiar with ConTeXt.

If you see https://www.ntg.nl/maps/36/09.pdf page no. 28 then proof is defined as

\defineenumeration [proof] [ text=Proof, number=no, headstyle=italic, title=no, %this is the default closesymbol={\mathematics{\square}}, style=normal]

But the closessymbol does not work.

I will create a minimum working example and post it as soon as possible.

This works here: \defineenumeration   [proof]   [closesymbol={\mathematics{\square}}] \starttext \startproof \samplefile{lorem} \stopproof \stoptext Wolfgang

I will pass something like n, 5, 10 etc.

A simple alternative to tikz is the usage of \framed. \define[1]\oldfact   {\inmframed[frame=off,strut=no,leftframe=on,bottomframe=on]{#1}} \starttext \m{\oldfact{n}} \stoptext Wolfgang

Hi! Not by computer, and I'm sure Hans (or Wolfgang) has already shown a way to do the old factorial with the actuarian mechanism when I'm back to the computer... /Mikael Den ons 27 dec. 2023 13:49Shiv Shankar Dayal skrev:

Thanks a lot. It should work nicely.

I tried this for old style factorial, but it appears much below the line in which it is used. How can I bring it up?

Replace the \inmframed command with \mcframed. \define[1]\oldfact   {\mcframed[frame=off,strut=no,leftframe=on,bottomframe=on]{#1}} Wolfgang
