Sorry - obviously didn't make myself clear. I meant looping through the @refnos array (with foreach) to print, not looping through the @data array; in the example, the @refnos array is superfluous although it is probably doing more in the whole application - or at least I hope it is.

I wasn't actually aware - or had forgotten - that split could be limited like your CountZero's example. Every day I learn something (or am reminded of it) is a day not wasted. Or something.
