try something like:
Code:
ctcp *:*:*: {
if ($1 == PING) { 
blah
}
}

..should halt all other ctcps and just execute "blah" when you re pinged.
(if the imaginary "else halt" that mirc should "add" doesn t work for some reasons just try
Code:
...
if ($1 != PING) { halt } 
else { 
blah
}
...

*shrugs*

return is the movement of sense.
