I'm trying to follow

to get a script L in math mode (to denote Laplace Transform) but to no

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:

%%%%%%%%%%%

\starttypescript [math] [modern,computer-modern,latin-modern,ams,palatino] [size]

\definebodyfont [17.3pt,14.4pt,12pt,11pt,10pt,9pt][mm][mc=rsfs10 sa 1]

\definebodyfont [8pt,7pt] [mm] [mc=rsfs7 sa 1]

\definebodyfont [6pt,5pt,4pt] [mm] [mc=rsfs5 sa 1]

\stoptypescript

\definefamilysynonym [default] [scriptfamily] [mc]

\def\scr{\fam\purefamily{scriptfamily}} % To use ${\scr ABC}$

\def\script#1{{\scr#1}} % To use $\script{ABC}$

\definetypeface [modern] [mm] [math] [modern] [ams] [encoding=texnansi]

\setupbodyfont[reset,modern,14.4pt]

\starttext

\input knuth

${\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$

$\sum_{\scr ABCDEFGHIJKLMNOPQRSTUVWXYZ}$

\startformula

\sum_{j \in \scr M} {\scr L}_{j} = {\scr P}.

\stopformula

\stoptext

%%%%%%%%%%%

Best regards: OK
