Some time back Wolfgang advised me to use statements like this:
\definefont [titlefont][MyriadPro-Bold*default at 70bp]
I cannot find what the *default parameter does. Can someone educate
me?
When you use a font in MkIV you have to specify which features of the
font should be enabled/disabled, to do this you define first a list
for them with the \definefontfeature command, e.g.
\definefontfeature[myfeatures][liga=yes,onum=yes,___]
For the main fonts in the document which are loaded with
\setupbodyfont these settings are applied in the typescripts, e.g.
\defintfontsynonym[Serif][MyRegularFont][features=myfeatures]
but when you load a single font with \definefont you apply
the list as argument to the font name after the asterisk.
When you want only a bigger version of the serif or sans version of
your document you can say \definefont[SansBold at 70bp] without
applying the list of features because the are already set in the
typescripts.

Is there a document or documents whare all this knowledge is
dispensed?

I hesitate to trouble you with a string of questions,
one by one. Right now the two critical files are:
\input formatting.tex
-----------------------------------------------

\usemodule [simplefonts]
\definefont [titlefont][MyriadPro-Bold*default at 70bp]
\definefont [subtitle][MyriadPro-Bold*default at 25bp]
\definefont [gauthor][MinionPro-Regular*default at 25bp]
-----------------------------------------------
followed by:
\input title.tex
---------------------------------------------
\startstandardmakeup[align=middle]

\startstyle[titlefont]
  Classic COBOL
\stopstyle

\vfil

\style[subtitle]{A Concise Guide}

\vfil
\null
\vfil
\style[gauthor]{John Culleton}
\vfil
\style[subtitle]{Wexford Press}
\stopstandardmakeup
--------------------------------

And the error messages indicate that MKIV cannot find those otf
files but they exist in /usr/share/fonts/OTF. The run completes
but other fonts and sizes are used for the title page.
