Context alternative for Latex's \overset & \underset

Context alternative for Latex's \overset & \underset

[WN]

Hi,

In doing my Latex to Context conversion, I stumbled on two Latex math 
commands : \overset and \underset
as in

\mathcal{T} = \overset{\infty}{ \underset{r,s = 0}{\cup} } \: 
\mathcal{T}^{r}_s

The page http://wiki.contextgarden.net/Math_with_amsl mentions the 
commands stackrel and underset
when using the AMSL module from Giuseppe Bilotta.
I tried to load the AMSL module with \usemodule[amsl] like to test
its workings.

\usemodule[amsl]
\starttext
\startformula
T = { \underset{r,s = 0}{\cup} } \:  T^{r}_{s}
\stopformula
\stoptext

but the log file indicates it cannot find the module amsl ???
Is the AMSL module not part of the standard Context distribution ? I 
thought it was.

I am using ConTeXt  ver: 2006.07.24 10:49  fmt: 2006.7.27  int: english  
mes: english.

Kind regards
Wim Neimeijer

Why not simply use

\mathcal{T} = \bigcup_{r,s=0}^{\infty} \mathcal{T}^{r}_s

You can either download t-amsl from http://modules.contextgarden.net/

No it is not part of standard distribution.

I have a question to other users of amsl module (since GB is no longer 
active on this list). Can the module be considered obsolete now that 
most (all??) features are part of Context.

$ kpsewhere t-amsl
/usr/share/texmf-tetex/tex/context/maths/t-amsl.tex

and that's the only one ('locate amsl.tex' confirms it).  The
/usr/share context tree is the ancient version that comes with tetex
3.0 (Context 2005.01.31 I think).  My ~/texmf tree has the newer
Context 2006.07.24 and it lacks t-amsl.tex.  Also the cont-tmf.zip
file doesn't contain it.  So it looks like it's not part of the
distribution.

I've attached the old t-amsl.tex in case it works for you.
