<p>Generates an error or a warning. If the value of the <var>expression</var> is 500
|

|
|
or more, <code>as</code> will print a warning message. If the value is less
|
||
|
|
than 500, <code>as</code> 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.
