Why replace don't work?

[Halemani]

Hey guys why replace is not working?
I know how to make it work. But, the procedure is to initialize the array before replacing. It does make sense that you cant replace, if it does not exist!
But is there no other way?

You aren't initializing anything...you input an array with no elements...Use the initialize array function for that anyways, instead of constant.

You can add elements to an empty array, but you cannot replace an element that doesn't exist.

I haven't seen your code, but I have to agree with Jim 🙂

Hey also can I change the size of an array dynamically. i.e, run-time.

[Halemani]

Sorry got it.
I will come up with some real problem!

[lmtis]

Sure.  Look in the array palette.  You can add to an array, get an array subset, etc.

Yes, using Insert into Array will resize your array. (if you just want to make the total length longer, and continue to replace items, you can basically insert another initialized array at the of the current one).
