If the Index Input Terminals of an expanded Index Array primitive are not wired, the first index defaults to 0 and subsequent indexes increment sequentially. Similarly, if the first index if wired to some value and the remaining are unwired, those remaining also increment sequentially beginning from the first wired index. This makes it easy to extract a sequence of N sequential elements from an array. However, an In Place Element structure configured for Array Index/Replace Elements requires all its index inputs to be wired. This forces the wiring of 0,1,2,3,4,5 constants when one wishes to replace the first 6 elements of an array for example.
