How to Use This Manual

Using Functions

This manual describes the functions supplied with your Information Builders product. It is intended for application developers who call these functions from their programs to perform calculations or manipulate data. Other users who access corporate data to produce reports can call these functions.

This manual also explains how to create functions tailored to individual needs (called subroutines) for use with your Information Builders product.

How This Manual Is Organized

This manual includes the following chapters:
