    I thought that at first. But then I realised that they might be deliberately autovivifying the second element of the array.

      But that is the root of the OP's problem. They apparently want to increment those 'M01...' strings, relying on the magic of ++.

        ...or maybe they want to add some kind of counter in the second element of the array.

        Who knows? There's not enough information. Any assumptions that we make are just... er... assumptions.
