About This Document
This Functions and Expressions Reference Guide contains information about the
expressions, functions, and reserved words that can be used to create component
rules in the Type Designer and map rules in the Map Designer.
The Examples directory, located in your default installation directory, contains
type trees and maps that can help you learn how to accomplish your mapping
tasks. These type trees and maps contain component and map rules that show the
use of many functions and expressions.
This document assumes that the reader knows the Windows environment, has
used the Mercator Design Studio, and understands words such as mapping, type
trees, and other basic Mercator terminology.
