Subject: RE: Optional parameters in UDF's
| 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;
| }
