Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
Recursive function to generate a random string of characters of specified length. Don't use this in a calculation field, since Filemaker will evaluate the numeric "Random" function each time you refresh the calculation. This is helpful in a script step or auto-enter calculation for creating paasswords, for example.
