1-6 FileMaker Pro Developer’s Guide
External function plug-in examples
There are three sample plug-ins included with the FileMaker Pro
Developer Edition:
1 a template example, which is a good starting point for plug-in
development
1 a fully functioning plug-in, which has documentation and commented
code
1 a folder of external function plug-ins created by third-party
developers
The template plug-in includes a function that converts characters to their
ASCII equivalents (and vice versa). For more information, see Read
Me-EFP Template:

Examples\Template\Read Me-EFP Template.
The fully functioning plug-in features four calculation functions:
1 The Xpl-Version function returns the plug-in version number.
1 The Xpl-BigPI function returns pi to the fourteenth digit.
1 The Xpl-Format function is useful for moving numbers into a phone
number format. It also provides an example integrating the
FileMaker Pro Application Preferences dialog box with a plug-in.
1 The Xpl-NumWords function returns the text equivalent of a number
(similar to a checkbook format). Although this calculation could be
created within FileMaker Pro, the result can be calculated more
quickly by using the External function plug-in.
