How to capture exception in AutoLISP?

[cracksther]

Hi all,

the following message is returned:
"Command: ; error: Unknown exception occurred
; warning: unwind skipped on unknown exception"
this occur because of following situation:
- in the file "A", is running a AutoLISP code that create a new file "B";
- in the file "B", a reactor, call other code that create details of a 3d, and return for the file "A",
- this all is run perfect; however if user close the file "A" before display manualy, of file "B" (ctrl + tab) the exception is returned in file "B"

Is possible prevent this exception?

Thanks!

This is not an AutoLISP error message, but seems to be something emanating from the native AutoCAD code, therefore I don't think you can "intercept" it (except maybe if it is a custom ARX or something and you have the source code), buit rather make sure to do the things the right way.
