  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This recursive function swaps out arabic numbers with roman numerals.

You have the option of indicating multiples of 1000 over 3,999 with either parenthesis or an overline over the letter. e.g. (XIV)CCII = 14,202

For numbers that are 0 or less, it will return "N" which stands for null.

This function can calculate roman numerals for numbers up to 3,999,999.

Requires FileMaker Pro version 10 or later to use the "Char" sub-function
