I'm not shocked that ColdFusion does it once I stopped and thought about it.

Re: Shocked!
I do not really see anything bad with leaving off the arguments scope even though I never do it. What amazes me is when I see a UDF that references a variable within the variables scope of the page calling it. An example is this current app I have been brought in on recently. Within the applciation.cfm it has some UDFs and within one of those it has things like #someVar# well #someVar# is not an argument nor is it even a variable set within the page. What it is, is some variable set on some page within the application that later calls that UDF. Things like that are fun to go and debug, fun if you like headaches. Things like that are also why I tend to always put in a scope if one is available to put in.

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.

Re: Shocked!
Railo has exactly this setting. 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: SELECT name, firstname from addresses name: #firstname# #name# 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: name: #getAddresses.firstname# #getAddresses.name# 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").

Re: Shocked!
Hardly shocking. Nor dangerous. coldfusion looks at the arguments and var scoped variables FIRST, and prevents you from creating var scoped variables with the same name as arguments. So it's no more or less dangerous than anything else CF does with regards to variable scoping. I'm not very consistent about prefixing arguments variables with "arguments." in my code... off the top of my head, I can't tell you when I do it and when I don't.. I can only say that I do it sometimes, and other times I don't :) Rick ~| Upgrade to Adobe ColdFusion MX7 The most significant release in over 10 years.

Re: Shocked!
Well yeah, I meant more the restriction etc I tend to scope them all anyway, just force of habit but for ColdFusion to have a strict / non-strict policy would be a step backward I think.

Re: Shocked!
How would that be dangerous? Because of potential collision with a variable of the same name in another scope? Is the order for var name resolution the same within a cffunction as it is elsewhere? Does the arguments scope not get checked first inside a cffunction? >a scope prefix.
