It depends what do you want to achieve, local changes can be done with \os, but this will use numbers from the math font. Mark IV has a new the new option "fontfeatures" and you can use this to get the oldstyle numbers from the latin modern OT fonts. Option one is to redefine \os to use the numbers from the main font, you have to put the following command in your document, \def\os{\setfontfeature{oldstyle}}, option two is to write \setfontfeature{oldstyle} in the preamble of your document and ConTeXt use oldstyle numbers by default if present in the current font. There is currently no better way to enable oldstyle number for the whole document except you define your own typescripts and use them.

Thnx in advance!

That's exactly why \os is almost useless (it messes up itemizations and other stuff); better to \switchtotypeface, even for local changes.

I spent hours today writing and debugging a huge typescript for lm (all those optical sizes, since i could not for the life of me get it to piggy-back the def's in type-siz). I just got it working flawlessly a few minutes ago -- sublime, a work of art even -- then I get your message which would have saved me hours of work! I just needed that one command!!! You're an angel, just wish I got this this morning ;-) Best wishes Idris PS Note that tnum (tabular version) looks better than onum alone, but is a function of onum in the font so cannot be invoked unless onum is invoked first. -- Professor Idris Samawi Hamid, Editor-in-Chief International Journal of Shi`i Studies Department of Philosophy Colorado State University Fort Collins, CO 80523 -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/

No, you don't have to, because oldstyle is predefined in type-ini.tex, two other predefined fontfeatures are "default" and "smallcaps" :-)

\definefontfeature[tnum][tnum=yes,onum=yes]

Hmm, I assumed the order would be [onum=yes,tnum=yes], or does the order not matter?

It did work for me but I got a error message for the next line, <errormessage> error: ...2tex/share/texmf-local/tex/context/base/font-otf.lua:2018: attempt to index field 'description' (a nil value) . l.12 ? </errormessage> My testfile: 01 % engine=luatex 02 03 \definefontfeature 04 [oldstyle] 05 [liga=yes,kern=yes,tlig=yes,trep=yes,onum=yes] % texligatures=yes,texquotes=yes 06 07 \setfontfeature{oldstyle} 08 09 \starttext 10 11 123456789 12 13 \stoptext I could set "tlig=no" and the error message vanishes.

I think not in this case, but a few OpenType features disable other (e.g. onum and lnum) and the order could be in souch a case. Wolfgang

Possibly because the predefined one does not have "mode=node", which seems important. I get: error: /opt/tex/texmf-local/tex/context/base/font-otf.lua:2019: attempt to index field 'description' (a nil value) followed by an assertion error. Best wishes, Taco
