Both are written as efficiently as possible (assumed because no point otherwise). I would like to know which of these is more efficient.

As I recall the profile included info on number of times a function is entered, total time spent in the function, and maybe min/max times in the function. You only need to add the profile option for the code you are interested in. And perhaps at the link stage also. Jon -- Jon H.
