How to tell if an array is full

[mjmnyr96]

I've noticed that if you try to use one of the built in functions, such as minval on an array that isnt full you get ???????? as a result. If I have a ten element array, how do I ask if element 10 is full? Thanks.

I lost my internet connection after posting this. I should mention that it is an array of reals.

If you know how many items you have put into the array, when the item count is equal to the size of the array, then it is full. You may not know how big an array is when it is passed into a function. In that case, you need to keep an item count and pass that item count into the called function.

Awesome, never thought of that as a way around it. Thanks a bunch.
