drowning in REACTORS (close lisp)

I am overwhelmed... bleh...

I have spent the last 4 hours trying to make heads and tails... my goal
is simple... I want to be smarter than my CAD workers are lazy..!!

I have a LISP routine that works perfectly, it updates my save stamp on
command. I know about blocking the save commands, but what about when
the user "X"s out of the program... nada... I am sure that reactors
are the right direction.

I would like to be able to get a better grasp, any pointers?? maybe
somebody has an example of what I am asking for...??

Thanks a ton in advance

 

here is some code I did to react to the begin save event

;SET UP REACTOR

(vlr-editor-reactor nil
'(vlr-beginSave . SAVE-LSTL))
)

; SET UP CALLBACK FUNCTION TO SAVE LIST OF LAYERS

(defun SAVE-LSTL (calling-reactor commandInfo / dwgname)
(put-layer-state-in-dictionary)
(PRINC "\nLayer state saved. Thanks for using LyrChk")
(princ)
)

Now, you can sub in your code to the SAVE-LSTL function or rename that function alltogether.
What I want to know is why I get crashes once in a while when the drawing closes.
It is not my functions that are crashing, its like I need to release the reactor or something before the drawing
actually closes.

Please fill me in so both of us can use this incredibly slick capability of the vlr-editor-reactor function.

James,

According to the help docs, that nil argument can be set to non-nil.
Would you know what happens if you set it to a non-nil value? And what
type of variable should be used - string, interger, real??

Cheers
Mike

 

The help file did not help me on that.
I have no idea what the data param is but I have a feeling you could find out by looking at the garden path example in
the vlisp tutorial.
Sorry for such a lousy answer.
