Topic: vl-exit-with-value

Hi guys,
I was wondering how this vl-exit-with-value funciton works and why it doesn't return the expected result.
Here are the tests I did:

Code - Auto/Visual Lisp: [Select]

1. ; Returns... nothing
2. ; _$ (test) -> _$
3. (defun test ( / )
4.   (vl-exit-with-value 3)
5. )
6.  
7. ; Returns... nothing
8. ; _$ (test) -> _$
9. (defun test ( / *error* )
10.   (defun *error* ( m )
11.     (vl-exit-with-value 3)
12.   )
13.   (/ 1 0)
14. )
15.  
16. ; This one errors out, and returns.. nothing
17. ; _$ (test) -> _1$
18. (defun test ( / *error* )
19.   (defun *error* ( m )
20.     3
21.   )
22.   (/ 1 0)
23. )

I was expecting to stop the routine and return this value of 3 
My intention was to use it inside an 'unstoppable' iterator like foreach / repeat / vlax-for, get the required item I need - and stop the same iterator by exiting (vl-some behavior).

This function is for use specifically with VLX applications which are compiled to a separate namespace, and is used in order to return a value to the calling function (which resides in a different namespace to the VLX application) - see here for a brief explanation of namespaces.

Thank you, Lee!
Looks like its not that simple as I've thought - since I didn't knew/heard about namespace(s).

You're most welcome - although you are not currently at the stage of working with namespaces, this thread at least serves as an explanation for others unsure of this function.

Indeed,
I wasn't aware that some functions require additional details - thankfully you are here to explain more about LeeSP.
