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#" = "Test Value2"> |
Also, the following lines are equivalent:
<cfset "myVar#i#" = myVal> SetVariable("myVar" & i, myVal) |
