Function Notes and Considerations

When using functions, keep these guidelines in mind:

Function names are not case-sensitive but it's good practice, to mix the case of function names for readability.
When using functions to format data for display, surround the entire function with pound signs and include them within a CFOUTPUT block.
Functions can be nested.

For example, you may display the system date value using the Now() function and format the displayed system date using the DateFormat function.
