Re: Sorting arrays

I use one physicla file tro sort subfile columns. This is a general purpose file which can be used in any program which requires a subfile sort.

See www.rpglanguage.com/iseries_rpg_sort.html for the relevant DDS and RPG

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

http://www.martinvt.com/Code_Samples/SFL_Sort/sfl_sort.html

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?
