When presented with this error message:

Encountered "exit ;" at line 22, column 13.
Was expecting one of:
"if" ...
"for" ...
"delete" ...
"insert" ...
"inserthtml" ...
"share" ...
"unshare" ...
"%>" ...
"input" ...
"." ...
"=" ...
":" ...
"hide" ...
"show" ...
"clear" ...
"enable" ...
"disable" ...
"select" ...
"set" ...
"info" ...
"alert" ...
"success message" ...
"sendmail" ...
"cancel" ...
"return" ...
"(" ...

I was wondering what return does.

Anyone?
