  77. anywhere on a line, unless the <samp>--bitwise-or</samp> command-line option

  78. has been specified.

  80. <p>An asterisk (&lsquo;<samp>*</samp>&rsquo;) as the first character on a line marks the

  86. <p>A hash character (&lsquo;<samp>#</samp>&rsquo;) as the first character on a line also

  87. marks the start of a line comment, but in this case it could also be a

  88. logical line number directive (see <a href="Comments.html#Comments">Comments</a>) or a preprocessor

  89. control command (see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>).  If the hash character

  90. appears elsewhere on a line it is used to introduce an immediate

  91. value.  (This is for compatibility with Sun&rsquo;s assembler).
