$$ is a construct which allows you to halt the script if the identifier returns $null. If used correctly it's a very short and simple way to halt a routine if a parameter is $null.
Note: $$ is not executing a /halt, it's effectively a way to halt completely the script execution, just like /halt, except that /halt also implies /haltdef, whereas $$ does not. This can be used inside events to /halt without /haltdef'ing. You can use the construct '$$null' for example.
