Using CFScript statements

The following sections describe how to use these CFScript statements:
•
Assignment statements and functions
•
Conditional processing statements
•
Looping statements

Using assignment statements and functions

CFScript assignment statements are the equivalent of the
following form:
lval = expression;
lval is any ColdFusion variable reference; for example:
x = "positive";
y = x;
a[3]=5;
structure.member=10;
ArrayCopy=myArray;
You can use ColdFusion function calls, including UDFs, directly in CFScript. For example, the
following line is a valid CFScript statement:
StructInsert(employee,"lastname",FORM.lastname);

Using conditional processing statements

CFScript includes the following conditional processing statements:
•
and statements, which serve the same purpose as the
if else
tags
•
,
switch case
and
cfdefaultcase
