I just noticed this test file failing:
\starttext $f'(x)$ \startformula f^\prime(x)\quad f'(x) \stopformula \stoptext
It gives:
! Undefined control sequence. l.4 f^\prime(x)\quad f' (x)
This is a typo in math-pln.tex. The end of the file should be
\bgroup \catcode`\_ = 13 \catcode`\' = 13 \doglobal\appendtoks \let_\activemathunderscore \let'\activemathquote \to \everymathematics %<--- was \everymath \egroup
ok, fixed ... the _ thing is kind of weird and taco and i could not cook up a reason why plain does/needs that ; the ' (prime) is needed this trickery is related to a change in the catcode management of context (which interferes with some plain tex left-overs) 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 -----------------------------------------------------------------
