The scripting language has an assortment of intrinsic (i.e. built-in) functions that can be used for various purposes. Some intrinsic functions operate on strings, while others operate on numbers. Some intrinsic functions return strings, while others return numbers.
The purpose of intrinsic functions is to provide authors with re-usable mechanisms that can be used to perform script operations that arise on a recurring basis. For example, the Kit includes intrinsic functions for searching string, carving up strings, comparing strings, and replacing text within strings. Intrinsics are also included to determine the minimum or maximum of two values, round a number off at a certain level of precision, and generate a random number.
The complete list of intrinsic functions provided by the language is presented below.
length number length(string str)
Returns the number of characters in the string str.
