Taco, thanks so much! I really appreciate the wonderful ConTeXt  
community without whose help I would never have been able to even get  
started.

\Gf is later used in the macros to define the Greek font. When defined  
with the \definebodyfont alternative, this works; when I try the  
\definefont, I get this error message:

! Undefined control sequence.

?

It looks like \MyFont doesn't get expanded when the \definefont command  
is read, but this is an area of TeX that I find especially opaque...

Yes, this works and is just what I want. Great!

Thanks a lot, Taco!
