Laurent, use strict; would have caught your typo.

Not really, Bill, since I did not try to run or even to compile the code. In my view, this was just a small code snippet showing changes compared to the original program, not a full program. But sure, I always use strict and warnings when I write actual programs. Thanks you for mentioning the typo.
