Variables not created in statistics

[math7]

Hello, yes I understand you Tim. Well I do not know the truth as it implements that at the system level as if you know that you are working on the development of the Prime. It might be that these column names actually are as global variables, so you can use them for example in a program that calculates them or can be used in other formulas or in the Solution application when solving some equations and that the variables are those names of the columns. I do not know maybe if enclosing that in single or double quotes that the calculator understands they are variables or something. Now, as Helge Gabert said, if I write the name of the column in the Home or in CAS because the list of values appears, but it is slow and tedious if there were many names that are used because they are not listed somewhere, but as you say maybe they will solve it soon in an update.
