    The capability to create and store your own calculations for use throughout your application is now available if you have FileMaker Developer 7. Custom functions are essentially the same concept as creating external plug-ins that developers have been creating using C++. However, don’t misunderstand the custom function capabilities. You are still limited to the FileMaker calculation engine functions and you have to re-create the custom function for each database. Therefore, there is still a place and a time for full-fledged plug-ins to perform tasks otherwise not possible for FileMaker Pro. This article will explore how to create a custom function. To get you started creating your own custom functions, the demo database will provide you with access to 21 of the most common and difficult calculations that developers use on a routine basis.
