// randomizes a ¶-seperated list // // ElementList CR-Separated List, e.g. "1¶2¶3¶4" // PermList For recursion, always set to "" Case ( ValueCount (ElementList)> 1; Let([ rnd = Round ((ValueCount (ElementList) * Random)+,5;0) ]; Permutation ( LeftValues ( ElementList; rnd -1 ) & MiddleValues ( ElementList ; rnd +1 ; ValueCount (ElementList)-rnd ); MiddleValues ( ElementList ; rnd ; 1 ) & "" & PermList ) ); ElementList & LeftWords( PermList ; 99999999) // Remove trailing CR ) Click to copy

This function shuffles the lines of a multi-line input.
Due to FM8's 10,000 recursive function call limit, no more than 10,000 lines can be shuffled with this function.

The second parameter is only used for recursion and should always be set to "", otherwise you may get unexpected results.
