I think every time, since it's the second argument. If it doesn't matter, you can do "for i = dcount(array,@fm) to 1 step -1" to have it evaluate once.

Or is UniVerse these days intelligent enough to keep track of what's going on? e.g. for i = 1 to dcount(array,@fm) *commands here next i versus totalattributes = dcount(array,@fm) for i = 1 to totalattributes *commands here next i Apart from readability and perhaps easier debugging is there an actual internal difference? I know it was an issue on older pick releases but I cannot remember if it ever affected UV?
