How do you specifiy the Default value for undefined array elements

[viScience]

According to the LV help, arrays have two defaults, the normal default and the default for undefined array elements.  

I presume there must be a way to specify the later default but I cannot find it anywhere.  Any ideas?

Hmmm, I don't like their choice of wordings.

I would call it uninitialized, not undefined.

Unless of course an empty array container is considerd "undefined"

I know you can drag the element out of the array container.  Change the default on that scalar element.  Then drag the element back into the array container.

Thanks!  I tried setting the default in place, making a typedef, etc but did not think to drag it out and back in again.

In case it's not clear - the value for uninitialized elements is an edit-time only thing and really only makes a difference in what value is filled in if you, say, modify element 6 without previously definining elements 0-5. If you index an undefined element in your code, you'll still get the default value for the datatype (ie, 0 for a numeric) regardless of what you set the uninitialized element value to be.

... and to make things much easier in the future, please vote for this idea. 😄

That's what this idea was trying to address. 😉
