1. Create an array : DIM Array$(320)

2. Put a value into each slot :

_MaxItems = 320
for a = 1 TO _MaxItems
  Array$(a) = MID$(STR$(a),2)
next a

3. Jumble them up as much as you want :

for a = 1 TO 1000
  Pointer1 = RND(_MaxItems)
  Pointer2 = RND(_MaxItems)
  swap Array$(Pointer1),Array$(Pointer2)
next a

Voila !! (French for "there's a bug here somewhere but I haven't found it
yet)
