CFScript example
The example in this section uses the following CFScript features:
•
Variable assignment
•
Function calls
•
For loops
•
If-else statements
•
WriteOutput
•
Switch statements
The example uses CFScript without any other ColdFusion tags. It creates a structure of course
applicants. This structure contains two arrays; the first has accepted students, the second has
rejected students. The script also creates a structure with rejection reasons for some (but not all)
rejected students. It then displays the accepted applicants followed by the rejected students and
their rejection reasons.
