+@cindex XStormy16 line comment character
+@samp{#} is the line comment character.  If a @samp{#} appears as the
+first character of a line, the whole line is treated as a comment, but
+in this case the line can also be a logical line number directive
+(@pxref{Comments}) or a preprocessor control command
+(@pxref{Preprocessing}).

+line.
