+Summary: All functions in Microsoft.VisualBasic assembly MUST set the error information (Err object) before throwing the exception
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+All functions in Microsoft.VisualBasic assembly MUST set the error
+information (Err object) before throwing the exception.
+For example, in the Right() funtion, if a negative number is passed as the
+length we must set Err.Number = 5, before throwing ArgumentOutOfRangeException.
+
+Steps to reproduce the problem:
+1. Have to cook some test code, yet!!!
+2. 
+3. 
+
+Actual Results:
+
+
+Expected Results:
+
+
+How often does this happen? 
+
+Always, we've not implemented any of it

+Bug problem description is inappropriate; as shown by the following 
+sample, this is not the Right() method but EITHER the exception 
+itself who sets up this err.number OR it is the Err object itself, 
+that is wrapping the different exception classes into numbers
+
+Code below runs on MS .NET with vbc.exe compilation:
+
+Imports Microsoft.VisualBasic
+Imports System
+Imports System.IO
+Public Class Test
+Public Shared Sub Main()
+	ErrObjTests
+	Console.Readline()
+End Sub
+shared sub ErrObjTests
+try
+	throw new ArgumentOutOfRangeException ("blah") ' --> No. 5
+	throw new OverflowException ("blah") ' --> No. 6
+	throw new Exception ("blah") ' --> No. 5
+
+catch ex as exception
+	If err.number<> 0 then Console.Writeline("ErrDescr=" & 
+err.description)
+	If err.number<> 0 then Console.Writeline("ErrNo=" & 
+err.number)
+Console.Writeline("Exception=" & ex.message)
+end try
+end sub
+End Class
