\mathop inside \sometxt in MKIV
Hi, I am using ConTeXt ver: 2008.09.10 14:01 MKIV fmt: 2008.9.11 and the following file \starttext \startMPcode label.bot(\sometxt{$\mathop{}$}, origin) ; \stopMPcode \stoptext gives ! Missing number, treated as zero. <to be read again> ## \purenumber ...firstofoneargument \@EA {\number #1 } \PDFobjref #1->\purenumber {#1} 0 R l.46 \def\PDFobjref# 1{\purenumber{#1} 0 R} ? ! Missing number, treated as zero. <to be read again> ## It runs correctly with MKII. Any ideas? Aditya

The problem is that everything within \startMPcode ... \stopMPcode is expanded, but \mathop's (re)definition has \let commands in it. This works as a workaround: \startMPcode label.bot(\sometxt{$\noexpand\mathop{}$}, origin) ; \stopMPcode But actually the definition of \mathop in font-ini.tex needs to be changed so that it won't be expandable any more. The current definition would give problems in the support files (tuo,tuc) as well. Best wishes, Taco

or \detokenise{a whole bunch of tricky tex}

indeed; i already did that, but more math commands might need that treatment Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
