Get line number of an error in JScript run in Windows Script Host - wsh

Question

Say, I have the following code that I run as a .JS file using the Windows Script Host:
try
{
ProduceAnError();
}
catch(e)
{
//How to get an error line here?
}
Is there any way to know the error line where an error (exception) occurred?

Sorry for my other reply. It wasn't very helpful :P
I believe what you are looking for is the ReferenceError's stack property. You can access it with the argument that you pass to the catch:
try {
someUndefinedFunction("test");
} catch(e) {
console.log(e.stack)
}
example output:
ReferenceError: someUndefinedFunction is not defined
at message (http://example.com/example.html:4:3)
at <error: TypeError: Accessing selectionEnd on an input element that cannot have a selection.>
at HTMLInputElement.onclick (http://example.com/example.html:25:4)

There isn't really a way to get a stack or even catch the line number programmatically. One can only see the line number when throwing an error. At best you can get the error code and description or you can make your own errors.
Here's the documentation.
And an example
try {
produceAnError();
} catch(e) {
WScript.echo((e.number>>16 & 0x1FFF)); // Prints Facility Code
WScript.echo((e.number & 0xFFFF)); // Prints Error Code
WScript.echo(e.description); // Prints Description
throw e;
}
