Whoops. It's a typesetting glitch. The two cases are supposed to read like
this:


--- ch2-07.l ---


%s MAGIC


%%
<MAGIC>.+ { BEGIN 0; printf("Magic:"); ECHO; }
magic BEGIN MAGIC;
.+ ECHO;
%%


--- ch2-08.l ---


%{
/* This example deliberately doesn't work! */
%}


%s MAGIC


%%
magic BEGIN MAGIC;
.+ ECHO;
<MAGIC>.+ { BEGIN 0; printf("Magic:"); ECHO; }
%%


Troff bites me again -- the lines that start with dots look to troff like
comments. I'll be sure to fix this in the next printing.

Thanks. I had a lot of typesetting trouble, largely because we discovered
fairly late in the process that the set of macros I was using on my machine
wasn't quite the same as the publisher's people were using. Aargh.
