The absolute easiest way I can think of to do this is to have multiple
logical files. Click a heading, rebuild the subfile using the logical that
is already sorted in that order. Click it again, read a different logical
sorted in the other order.

Subject: Sorting arrays
I'd enjoy following a discussion about sorting related arrays. I have
already solved the problem I am about to present, but as I look at my
solution it occurs to me that I am embarrassed to show my solution to
knowledgeable people. There _has_ to be a better way.
Here's the sceanrio: To display a multi-column load-all subfile and
have each column heading clickable. The click would determine which
column is sorted. A second click on a clicked column would sort the
column in the other direction.
There are images of this at

The code is also there. It works. But gads, its awful code.
So, lets define the problem a bit more? A load-all subfile with 5
columns of data How would one define the needed array(s), data
structure(s), or whatever(s) so that they can be sorted up or down by a
selected column?
