Surprise...

[jbv]

I made a test with the same loops and the same data on LC 6.5.2
desktop Mac, and arrays run 20% faster than items...
On LC9 server I get opposite results : items are 2 times faster then arrays.

As said in my original post, AFAIR U have always used arrays instead
of items & lines because it has always been faster, even with
multidimensional
arrays...
