Standalone, quick & dirty list sort order randomizer using recursion.

Sample Input:
shuffleList ( "1¶2¶2¶")
Sample Output:
"1¶2¶2¶" or "2¶1¶2¶" or "2¶2¶1¶"


 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Description:

Recursively generates a randomly re-sorted value list of the input list. Duplicate values are not de-duplicated (inputting "1¶2¶1" can return "2¶1¶1" but not "2¶1"). The usual FileMaker recursion limits apply - the function fails when the input list length approaches or exceeds 10000 values - FMPro's recursion limit is 10000 iterations. It relies on FMPro's "random" function for the randomisation - in FileMaker we trust...

Syntax: shuffleList ( listToShuffle )

In: listToShuffle - the return delimited list to randomly re-sort

Return type: Text (a return delimited list with the same values, but now in a randomly mixed sort order)

shuffleList ( "1¶2¶2¶") ---> "1¶2¶2¶" or "2¶1¶2¶" or "2¶2¶1¶"

I used this to create a database that generates Bingo Cards.. Any kind of Bingo, any number of cards, with the push of a button.
