Going back to the early days of PBP, before Microcode studio, to the days when you carved your code into slate tablets, there was an anomaly/bug with PBP sometimes handling math within array parenthesis. The workaround was to simply add a dummy argument (which goes to show how old that code is). Now I can't remember at which point the error was eradicated without compiling a bunch of test samples across more than half-a-dozen versions of PBP. The code I posted above pretty much works with all versions, though if absolute speed is your thing, you can probably lose the +0 if your PBP is relatively up-to-date.
