Re: Sorting arrays

The main problem with all those LFs is - all those LFs - lots of index maintenance going on - have to create yet aNOther LF to accomodate a new situation.

The use of data structure arrays is quite new - in terms of the last 28 years, anyhow. So it was necessary to use a different technique in days past. Now that is the simplest thing - read records into the array. There are issues of how many elements to have in the array, but those are manageable.

Hi Booth,

I have created similar programs, and I use a differenct LF for each type of sort, not arrays. It is much easier and cleaner this way, I think.



Thanx,

Nick

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?
