Hi Nadya.

>I don't understand, where this code should be put. Say, we have several applications, which are class based or form based and use their own Error method. These applications can invoke UDFs, what in turn have something like

>lcOldError = on('error')

>some code
>on error &lcOldError

We're suggesting either that the Error method of the object calling the UDF have this code in it or (a better choice) is to call a UDF wrapper class rather than calling the UDF directly, and the UDF wrapper class would have this code.
