There is a happy news here today. The use of raise exception is allowed again after I put some coding in using this convention:<div><br></div><div>exitcode, actual_result = f1()</div><div>if exitcode < 0: return exitcode</div>
<div>.... continue something useful with actual_result</div><div><div>exitcode, actual_result = f1()</div><div><div></div><div class="h5"><div><br></div><div><br></div><br><div class="gmail_quote">On Tue, Oct 5, 2010 at 7:15 PM, Nick S Kanakakorn <span dir="ltr"><<a href="mailto:bbdada@gmail.com" target="_blank">bbdada@gmail.com</a>></span> wrote:<br>
