[CQ-Contest] busted calls-what do do?

[Jan Erik Holm]

If you have busted calls in the log, how do you
do to claim no points for them?
There seems to be no way I can do so in my loging
program and also in the cabrillo file there doesn´t
seem to be a way to claim zero point for a QSO.
I can ofcourse just delete but that doesn´t seem
fair to me but on the other hand I don´t want to
claim points for something I just know is busted.
