Yeah, if it performs far far better then for sure, let's enforce it!

You can either let Railo scan all scopes like CFML, or for example the variables scope only. In addition in Railo you can turn off implicit query scanning as well. So you would recieve an error when you execute the following: <cfquery name="getAddresses" ...> SELECT name, firstname from addresses </cfquery> <cfoutput query="getAddresses"> name: #firstname# #name# </cfquery> My two notes on this. Not only is scoping variables easier to use, it is much more performant. Just imagine you would use a variable from the client scope without scoping it. CF would need to scan through 8 other scopes first in order to find it first. So to round up the example before just use: <cfoutput query="getAddresses"> name: #getAddresses.firstname# #getAddresses.name# </cfquery> Greetings / Grüsse Gert Franz Customer Care Railo Technologies GmbH [EMAIL PROTECTED] www.railo.ch Join our Mailing List / Treten Sie unserer Mailingliste bei: deutsch: http://de.groups.yahoo.com/group/railo/ english: http://groups.yahoo.com/group/railo_talk/ Gaulin, Mark schrieb: > Yeah, I wish there was an admin setting that would REQUIRE all variables > to be scoped (like VB's "Option Explicit").
