<p><a name="index-_0040code_007bfail_007d-directive-325"></a>Generates an error or a warning. If the value of the <var>expression</var> is 500
or more, <span class="command">as</span> will print a warning message. If the value is less
than 500, <span class="command">as</span> will print an error message. The message will
include the value of <var>expression</var>. This can occasionally be useful inside
complex nested macros or conditional assembly.
