Hi, Attached is a new version of math-ext - multiple columns - alignment per column See examples in source (mixed &|cr and NC|NR is no longer supported). That's all the math for this week. Hans

Yes it does. But when I place the \uchar{1}{01} inbetween the bla bla's the glyph remains regular.
Are you in math mode, by any chance? An very small example with wrong versus right would be very helpful. Cheers, Taco
Hi Taco, I am not in math mode. I am not sure what happened, but somehow I must have send my reply to the wrong thread. I have since send it to the correct thread, see \uchar and italics question. Sorry for the inconvenience, Sjoerd On 18 Jan 2006, at 08:47, Taco Hoekwater wrote:

Hi,
Attached is a new version of math-ext
- multiple columns - alignment per column
See examples in source (mixed &|cr and NC|NR is no longer supported).
Thanks a lot. This takes care of 95% of my math needs, and I have finally started using context for a project. I did a bit of testing of the code and things work as expected. Once it is included in the main distribution, I will write an entry on the wiki. I am not sure of what is distance supposed to do when we specify the columns as n=something. Consider the following example for the source. I changed distance=0pt to distance=5cm and see no change. \startbuffer \placeformula \startformula \startalign[n=5,distance=5cm] x &= yy &= xx &= yy &= zz \\ a &= b &= p &= q &= w \\ \stopalign \stopformula \stopbuffer \typebuffer \getbuffer Thanks Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

\startbuffer \placeformula \startformula \startalign[n=5,distance=5cm] x &= yy &= xx &= yy &= zz \\ a &= b &= p &= q &= w \\ \stopalign \stopformula \stopbuffer
\typebuffer \getbuffer
it's only used when m is set Hans
Hans et al, I am going to assume that all of this is saved as math-ext.tex. None of it goes anywhere else at the moment. Correct? Also, I assume that: \ifx\startalign\undefined \input math-ext.tex \fi still needs to go into cont-new.tex. Correct? On Jan 17, 2006, at 5:50 AM, Hans Hagen wrote:

Does this mean if I update I will have it in the core and I can get rid of the line in cont-new.tex? On Jan 23, 2006, at 1:51 PM, Hans Hagen wrote:
