There is no command for that. However, you could write a function for it. You need to know the number of instances the list contains. The best method for that is using functions that wrap both the New and Delete command, so they can keeps count of how many instances are created/destroyed.;count types global max=0 For t.MyType = Each MyType max=max+1 Next ;get random type id=0 For t.MyType = Each MyType id=id+1 If id=Rand(Max) then Return t Next |

| ;get random type That won't work. Rand will generate a new random number for each iteration, and its possible to get through the entire type collection without success.id=0 For t.MyType = Each MyType id=id+1 If id=Rand(Max) then Return t Next Call Rand once, before you loop through your types. |
