Usage
The following sections provide detailed descriptions of some of the uses for the
Calling Functions
When you use the cfset tag to call a function, you do not need to assign the function return value
to a variable if the function does not return a value or you do not need to use the value returned
by the function. For example, the following line is a valid ColdFusion cfset tag for deleting the
MyVariable variable from the Application scope:
<cfset StructDelete(Application, "MyVariable")>
Arrays
The following example assigns a new array to the variable
<cfset months = ArrayNew(1)>
This example creates a variable
<cfset Array_Length = ArrayLen(Scores)>
This example assigns, to index position two in the array
<cfset months[2] = "February">
Dynamic variable names
In this example, the variable name is itself a variable:
<cfset myvariable = "current_value">
<cfset "#myvariable#" = 5>
