However, there are ways of getting the effect you want: 1) Use "eval". I'm afraid this is not documented, I'll have to add that. But you can do eval $rsq eval 2+2 and so on: the result is computed, printed, and discarded. 2) Use "printf" (which is documented): printf "R-squared = %f\n", $rsq printf "%g\n", 2+2 As for the behavior with "smpl" -- yes, it would be nice to be able to use the sort of formulation you give. We'll work on that. Allin Cottrell
