<p>&lsquo;<samp>-f</samp>&rsquo; should only be used when assembling programs written by a
(trusted) compiler.  &lsquo;<samp>-f</samp>&rsquo; stops the assembler from doing whitespace
and comment preprocessing on
the input file(s) before assembling them.  See <a href="Preprocessing.html#Preprocessing">Preprocessing</a>.
</p>
<blockquote>
<p><em>Warning:</em> if you use &lsquo;<samp>-f</samp>&rsquo; when the files actually need to be
preprocessed (if they contain comments, for example), <code>as</code> does
not work correctly.
