Is there a simple command for reversing a series?
I appreciate that I could sort the entire workfile on the basis of a trend (in descending order), but I would like to do it for series individually and maintain the workfile structure. :?

Unfortunately not - it is assumed that once the data is in the workfile, then it has the correct structure.

You could copy it into a new page, reverse it using a trend, then copy it back.
