Forums Scripts & Popups halt event

what is REAL diference between halt and haltdef, i saw something in help file but i still cannot understand, can anyone nice explain it to me?

halt: halts a current executing script.
haltdef: halts mirc default display so you can create your own, e.g: using haltdef on join will stop mirc echoing anything, so then u can create your own.

okay. thanx much

np
keep in mind when using haltdef you have to prefix an event with "^" e.g:
on ^*:JOIN:#:{
echo -s $nick joined $chan
haltdef
}
