...ah yes, of course, thanks Jim - I forgot that 'delete item y' is not the same as 'delete item *called* y' !
So, would itemoffset help...? put "1,2,3,4,5,6" into theNumbers repeat until theNumbers is empty put any item theNumbers into n do something delete (itemOffset(n, theNumbers)) from theNumbers end repeat I realise that this may not be the most efficient layout (one more line than yours!) but it reads nicely and could help in educational settings when teaching the application of scripts to formulae that use finite n-based series - I'm thinking here about permutations (nCr), combinations (nPr), binomials, factorials, statistical analysis, etc. Just a thought and hopefully not too much of a hijacking of the thread :-) Best, Keith..
