Evaluating Functions

You can use a function in any expression. For example, the AlarmActive() function returns TRUE (1) if any alarms are active, and FALSE (0) if no alarms are active. In the following text object, either "Alarms Active" or "No Alarms Active" is displayed, depending on the return value of the expression.

Note: Functions return a value that indicates the success of the function, or provides information on an error that has occurred. In many cases (for example, when used in a command) the return value can be ignored. You need to use the parentheses () in the function name, even if the function uses no arguments. Function names are not case-sensitive: PageNext(), pagenext() and PAGENEXT() call the same function.
