Syntax
    <cfdump
       var = "#variable#"
       expand = "yes" or "no"
       label = "text"
       top = "number of rows or levels">

History ColdFusion MX 7: Added the top attribute. ColdFusion MX 6.1: Added the ability to dump COM objects; it displays the methods and Get and Put properties typeinfo information for the object.
Usage The expand/contract display capability is useful when working with large structures, such as XML document objects, structures, and arrays. To display a construct, use code such as the following, in which myDoc is a variable of type XmlDocument:
    <cfif IsXmlDoc(mydoc) is "yes">
       <cfdump var="#mydoc#">
    </cfif>
The tag output is color-coded according to data type. If a table cell is empty, this tag displays "[empty string]".
Example
    <!--- This example shows how to use this tag to display the CGI scope as a
    structure: --->

    <cfdump var="#cgi#">
