Hi Bruce -
I have done some more work on this, and I have made progress. As you and I
have both noted :-) I do not completely understand why it works. There are
some deep dark secrets in TeX! I have ordered a copy of Knuth's original book
on TeX.
The attached file is the latest version of my thconfig file.
The magic lines that make the date and Therion version into larger fonts are
98-99 and 156-157. I used the "-d" option when compiling, then looked at the
resulting file called "data.tex". It has quite a few lines using the \ss
macro. I adapted those lines and was pleased to find that it works.
The mystery, of course, is what exactly is the \ss macro doing? I did some
Google searches but the only pages I found refer to the special German
character ß which is obviously not how it is being used here.
I have not messed with the base-scale settings any further. I also have not
chased the problem where "debug station-names" leaks from one layout section
to another. Martin produced a test case that contradicts my experience. He
is using a different version of Therion than I am. More investigation is
needed.
