Maybe you wanted to say that according to the mathematical properties of the quartile, there can be no confusion. With respect to that, I would expect that determining which is the value associated to a property should be as easier as possible, independently of the expertise of the user. On the other hand, I think that fields should have unique identifiers in general, avoiding the need of consulting external documentation. I think I exposed my reasons. I will not insist more.

My point is about the labels in the summary, no the name of the variables. As far as I have read, documentation says In addition to printed output, the program stores the individual statistics into three sets of variables. Then it appears the description of the variables (in particular what you quoted), but it is not said that the order of the lines in the summary correspond with the same order than the description of the variables in the documentation.

Yes, I understand the error. My concern is because the following two options work. gnuplot> a="1" gnuplot> print a+a 2 gnuplot> sum = 0.0 gnuplot> do for [i=1:2] { more> sum = sum + a more> } gnuplot> print sum 2.0 I am not used to gnuplot developer ideas, but I would expect sum to support strings which contain numbers.

summation of strings
