Last element in array by -1 index

[stephenb2]

Return the last element of an array by indexing it with -1, as in myArray[-1].

For a bonus, the second-to-last could be returned by usinging index -2, etc.

Duplicate Idea.

Look at Negative Values in Index Array or Array Subset

But this is the TestStand Idea Exchange, not the LabVIEW IE.  Therefore, not a duplicate.

But those arguments against this idea are still valid.

TestStand supports negative array bounds though so this would not be possible without breaking backwards compatibility. Also, -1 is sometimes used for uninitialized index variables in which case a user might prefer to have teststand give an error to help them catch bugs in their code rather than have it give them the last element when that's not what they intended.

I think that (someone else might have to keep me honest here) TS is still missing reverse() as it pertains to arrays -- whether I can reverse a 1D array.  If reverse() was implemented (also important because 50% of the time I sort an array it will come out backwards) then you could use positive indexes against reversed arrays (might be a little slower, but doable).

Crossrulz,

You're right.  I didn't realize I wasn't in the LabVIEW exchange.
