I've read and have come to agree that it is not a matter of IF you can do something in Filemaker, it's just a matter of HOW. Filemaker Pro's scripting ability can solve unique problems, however constructing complex scripts to perform custom functions is difficult and time consuming.

Enter Brian Dunning's OSX Widget of Filemaker Pro custom functions. This widget is a searchable compilation of custom functions created using Filemaker's built-in scripting language.

Useful functions such as changing letters from lowercase to uppercase & vise versa, generating random numbers, password generation, parsing strings and more.
