Halts a script and prevents any further processing.
If used in a event with ^ prefix, will stop AdiIRC from showing the default text for that event.
Example
alias example { ;Echo 'some text!'- /echo -a Some text! ;Halt the script. /halt ;Echo some more text, but this line will never be executed. /echo -a This echo command will never execute }
