I'm trying to follow

to get a script L in math mode (to denote Laplace Transform) but to no avail. I followed the code in the first section, but I get the following compilation error. Any help is appreciated.

Hi Troy,

The following works fine for me in mkii, but not in mkiv since, as you observe, the command \purefamily seems to have disappeared from mkiv:

Sure, as we have a complete different model now as in mkiv we take complete freedom to divert from the regular tex approach of families. Anyhow, the following shoudl work out ok. You need the beta that i just uploaded as some extra checks were needed because these are non typical fonts. This is just a test. In order to have a nice solution we'd have to define a proper virtual setup (so in fact symbol then becomes a collection of alternatives; of course we can consider adding them the base lm set instead) \unprotect \chardef\msfam\plustwo % math symbol \def\c!ms{ms} \unexpanded\def\ms{\ifmmode\fam\plustwo\else\setcurrentfontalternative\c!ms\fi} \chardef\symbolmathmode\zerocount \def\enablesymbolmath {\chardef\symbolmathmode\plusone } \def\disablesymbolmath{\chardef\symbolmathmode\zerocount} \appendtoks \ifcase\symbolmathmode\or\dosetmathfamily\msfam\c!ms\fi \to \mathstrategies \enablesymbolmath \protect \starttypescript [math] [modern,computer-modern,latin-modern] \definefontsynonym[MathSymbol][MathSymbol-Regular@symbol-math] \loadfontgoodies[symbol-math] \stoptypescript \starttypescript [math] [modern,computer-modern,latin-modern] [size] % extras on top of regular and bold \definebodyfont [4pt,5pt,6pt,7pt,8pt,9pt,10pt, 11pt,12pt,14.4pt,17.3pt,20.7pt] [mm] [ms=MathSymbol sa 1] \stoptypescript \usetypescript[modern] \setupbodyfont[modern,10pt] \def\scr {\ms} \def\script#1{{\scr#1}} \enableboldmath \enablesymbolmath \setupbodyfont[10pt] \starttext \input knuth ${\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ $\sum_{\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ $\sum_{\mb ABCDEFGHIJKLMNOPQRSTUVWXYZ}$ \startformula \sum_{j \in \scr M} {\scr L}_{j} = {\scr P}. \stopformula \stoptext ----------------------------------------------------------------- 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 -----------------------------------------------------------------

Hans,

I updated my ConTeXt (by rerunning first-setup.sh and remaking the format files), but I get the following error when compiling your code.
