Re: How can I define my own trap?

Hi,

Thanks for your quick answer!

Now, I understand how to create the list with my own definitions but don't
know what your last line of each object definition means (::= { ncpstatus 2
} and  ::= { ncpcalleventsobjects 1 } respectively)  Is this related to how
should I retrieve the information from my database? I thought that it was
enough to define the type of the variable (integer, string...)

Could you clarify me that point please?
Thanks!
