David,
Everything in CF (starting with CFMX and partially before that) is an
"object" that has a "parent".
For example, if I do the following:
<cfset x = 10/>
I have created a "member" of the "variables" scope ("variables" is the
object and "x" is the member).
So I could do the following with x:
<cfoutput>#x#</cfoutput>
<cfoutput>#variables.x#</cfoutput>
<cfoutput>#variables[x]#</cfoutput>
This is true of every scope in CF - application, variables, form, url,
arguments, attributes, request, server, session..... Each of these are
objects with members.
Why does <cfoutput>#x#</cfoutput> work you ask? Because when CF sees a var
that has no parent object specified it looks in the variables scope
(followed by url and then form) and figures it out for you. This is done for
convenience but the abstraction keeps you from understanding what is going
on under the hood.

What is the [] for. How would they be used. I have never used them at all.

cfqueryparams.
I am just starting to write in the cfqueryparams. That is a new one too.
