Useful Custom FileMaker 8 Functions (Digital Short Cut) [PDF ebook] 

This Short Cut presents a sampling of custom functions that we’ve found useful, or that serve as good examples of functions in our day-to-day practice. The functions are broken into groups according to their purpose, much as File Maker’s calculation functions are. Please note that these functions are meant as examples-although the examples were not tested exhaustively, nor is this collection meant to be comprehensive. We hope you’ll find some of them helpful directly, or that reading and analyzing others might provide a springboard for your own ideas.
