Idoc Script has many built-in global functions. Functions perform actions, including string comparison and manipulation routines, date formatting, and ResultSet manipulation. Some functions also return results, such as the results of calculations or comparisons.
Information is passed to functions by enclosing the information in parentheses after the name of the function. Pieces of information that are passed to a function are called parameters. Some functions do not take parameters; some functions take one parameter; some take several. There are also functions for which the number of parameters depends on how the function is being used.
