You may be right there, as far as the system (I guess Apple, not TeX)  
is concerned, the switch back to upright may be considered a line

My own knowledge of plain TeX is limited, thanks for figuring this out.


Seeing this code makes me grateful the fontspec package exists.

Thanks, I was looking for something like this.

I would suggest a minor edit to the AAT-info.tex and OpenType-info.tex

Surround the \def\myfontname line with:

\def\myfontname{Hoefler Text Italic}

You can now call this file from a driver file:
\def\myfontname{Hoefler Text Italic}
\input AAT-info
and easily obtain any info you might like.

Now all I have to do is understand the symbols, and numbers in the  
output: Using the above example, what is the difference between a  
checked 'Line initial swashes [4]' and a non-checked 'Word Final  
Swashes [2]'. I guess that the [0] indicates that there are no  
characters present that fulfill the criterium, but I a short  
explanation may be helpful.

Classic has disappeared from my computer a long time ago.
