Variables not created in statistics

[math7]

I have noticed that in the application of statistics when you enter a name or title for column C1, C2, C3, etc; the title changes within the application, but no such variable is created. For example, instead of C1 change it by "time" and instead of C2 change it by "distance"; these names "time" and "distance" are not created as variables accessible by the operating system for use in another application or program. Only its original names C1 and C2 can be used which should not be so for that they are given proper names to those columns; it would be good to implement this in a future upgrade.
