To have an optional param in a UDF, don't declare it. For example, this
UDF has one required and one optional arg:
function greet(firstName) {
var lastName = "";
//did the user pass 2 or more args?
if(arrayLen(arguments) gt 1) {
lastName = arguments[2];
}
writeOutput(firstName);
if(lastName neq "") writeOutput(" " & lastName);
return true;
}
