+It is possible to embed Lout text inside program comments.  How this
+is done could in principle vary from language to language, but in
+every language supported so far it is done by starting off the comment
+with an @Code "@" character.  If the language has several ways to get
+a comment, this will work every way.  The entire comment after the @Code "@"
+character should then be Lout text.  For example, to force Lout to start
+a new page at some point within a C program, place
 @ID @Code "/*@ @NP */"
-at that point.  Or you could make a heading like this:
-@ID @Code "/*@ @Display @Heading { treeprint() } */"
-Other possible uses for this feature include index entries and margin
-notes.  Incredible as it may seem, you can even write
+at that point.  (In this case you can also simply include a formfeed
+formfeed. @Index { formfeed in program texts }
+character, control-L, without any comment; whatever the language, a formfeed
+in program text is taken to be a request to start a new page.)  Or, to
+make a heading in an Eiffel program, do this:
+@ID @Code "--@ @Display @Heading { treeprint() }"
+(Eiffel comments begin with @Code "--" and end at the end of the
+line.)  Other possible uses for this feature include index entries and
+margin notes.  Incredible as it may seem, you can even write
 @ID @Code "/*@ @CD @Heading { Function @CP { treeprint() } } */"
 with a @Code "@CP" symbol and some C code inside the Lout code
