I am pretty sure copyright has reverted to me. But the big problem is
that the only copy I have of the book is ... a copy of the book. I
don't have an electronic copy. I wrote the book using Troff (I even
wrote my own macro package to create the index, because there wasn't
anything to do that at the time), but the figures were created
separately when the book was pasted up. As I said before, I think the
only way to create an electronic version would be to scan in the
book.
Google Books appears to have scanned it, but only for searching (they
will only show you small parts of it, which they call "snippet
view"). I couldn't figure out how to get them to make the whole book
available (which they call "full view"). I've sent them an email;
I'll see if I get a response.
By the way, I misstated last night -- there are actually 7 reserved
characters, not 6. They are
{ } ' # . " `
In my defense, I actually only needed 6 -- I could have reused ` (back
tick) instead of # for the preprocessor, since ` currently is used
only inside of strings.
