[XeTeX] how to select fonts in math mode in plan TeX?

[John Was]

Hello

I think you want something analogous to the following (taken from some very 
old work in EmTeX):

\textfont0=\wwimrten
\scriptfont0=\wwimrseven
\scriptscriptfont0=\wwimrfive
\textfont1=\tximiten
\scriptfont1=\tximiseven
\scriptscriptfont1=\tximifive
\textfont4=\tximiten
\scriptfont4=\tximiseven
\scriptscriptfont4=\tximifive
\textfont5=\tximbiten
\scriptfont5=\tximbiseven
\scriptscriptfont5=\tximbifive
\textfont6=\tximbten
\scriptfont6=\tximbseven
\scriptscriptfont6=\tximbfive

The bits after the = signs are the various fonts that plain TeX will access 
in math mode.  After \txim (which was my abbreviation for 'Imprint tweaked 
for use in TeX' I have r for roman, i for italic, b for bold, and bi for 
bold italic.  At the end of the font names, I have 'five' for 5pt, 'seven' 
for 7pt, and 'ten' for 10pt.  If you follow this pattern for your preferred 
maths typeface (not necessarily using the same nomenclature) you should end 
up with roman, italic, bold, and bold italic for all the sizes that TeX will 
need to access in math mode.

Of course, one can see why this isn't how it's usually done these days!

John
