Example
<!--- This code shows assignment by-value and by-reference. --->
// This script creates a structure that StructCopy copies by value. <br>
<cfscript>
// Create elements.
s = StructNew();
s.array = ArrayNew(2);
// Assign simple values to original top-level structure fields.
s.number = 99;
s.string = "hello tommy";
// Assign values to original top-level array.
s.array[1][1] = "one one";
s.array[1][2] = "one two";
</cfscript>
<!--- Output original structure --->
