Who Called Function?

Hi Folks,

I am new to Revolution and was wondering if there is a way in a function to tell who called the function (i.e. I want to see the current call stack)?

I have a function that finds the correct connected database and returns its ID to the caller. If for some reason the database is not connected I want to consider it to be a logic error and notify the user of the error with information that would be useful to me (the developer) so I can more easily figure out why the error happened (not that I ever expect it to happen but I do tend to program defensively).

Thanks, Brian

Hi Brian,

The target returns the object that called the currently running handler.

Best,

Mark

Take a look at the executionContexts Brian. It returns the chain of calls leading up to the current spot in a script where it is called.

Hi Trevor,

That is exactly what I was looking for. Thank you very much.
