LongestString custom function

Author: Daniele Raybaudi

Returns the longest string of a given text and its length; if more than one string has the same length, it returns the last.
A string is definited as a space separated part of text.

I had to find a way to stop a bug of the good WordWrap CF by Jonathan Stark: it fails when the "size" parameter is lower than the longest word of the given text.

Hello, I tried implementing on a current text field, but cannot get an sample output. I created a new text field as calculation, and set it to use the custom function. Do I need to pass any parameters to the function?

You'll need to create a calculation field, result text.
Also you'll need the Advanced version of Filemaker.
