In essence, refering to variables outside the scope of a tag

parameters to a tag, and

I'm with you. When I raised this issue in December '99, Dave Watts
pointed out that just because you can do something doesn't mean that you
should.

This is always a matter of interest in my classes, i.e. where can one find a
definitive listing. The following Allaire Knowledgebase article names many,
but leaves off a few (IMHO), including:
Attributes.
Caller.
CFHTTP.
ERROR.
CFCatch.
Folks,
I have seen a mention on this list in the last couple of days something
called the request scope for CF variables. I had never heard of it. Until
now I had only heard of the Application, Client, Session, Form, Query, and
Attributes scopes as well as the local variable scope.
Now I have a

I can add in my two cents, although it probalby isn't the complete list.
The 'variables' scope is for local, or instance variables. They only
exist during the execution of the page which they are created (I.E.
with a CFSET, for example).
There is also the URL scope. (Is that a type of

: What are the recognized CF variable scopes?
Tim, I came across the mentioning of request variables in the fusebox
methodology book also you can find the usage of the request variables in the
code that makes up the fusebox.org site.
I am still very confused about the usage of the request variables
The more I hear people talk about this topic, the more I'm getting
curious about the request scope.
If you are using these 'local' variables that are accessible via custom
tags, doesn't that decrease the re-usability of your custom tag, if you are
counting on this 'global' variables
