[WM20] - How to randomize (shuffle) an array items order

Hello,

I am loading values to an array as entered by user.

After enters all the values I want to randomize the array elements order so the user entered values gets shuffled and they are not in the sequence as entered by user.

For this the online help refers to a function called ArrayMix but that function is not available in WM20.

How can the shuffle the values in an array in a random way order?

TIA
