Parameters
Usage
You can use direct assignment statements in place of this function to set values of dynamically
named variables. To do so, put the dynamically named variable in quotation marks and number
signs (#); for example:
<cfset DynamicVar2 = "ABD">
<cfset "#DynamicVar2#" = "Test Value2">
Also, the following lines are equivalent:
<cfset "myVar#i#" = myVal>
SetVariable("myVar" & i, myVal)
For more information, see Chapter 4, “Using Expressions and Number Signs,” in ColdFusion MX
Developer’s Guide.
