Hmm… certainly an interesting idea: put 1,2,3 into tVar myAdd 5, item 3 of tVar command myAdd pToAdd, @xAddTo put pToAdd+xAddTo into xAddTo end myAdd tVar = 1,2,8 I doubt we should get our hopes up Dar ;-) Of course if we can do that it means ruling out what I was suggesting as the chunk could mutate from one reference to the next. The case of a command mutating a single chunk is much simpler as it’s just a case of retaining the evaluation.
