Re: Sorting arrays

Read up on APIs QLGSORT and QLGSRTIO. I have used these in a couple of
programs where I couldn't just read a new logical file and reload the
subfile with new data each time I wanted to resort the subfile list. These
APIs allowed me to load the data from the subfile into it and sort it any
way that I wanted. I could then read the data in the resorted order from
the API and reload the subfile with the same data. This allowed me to keep
any options that user had keyed next to a subfile record,
but hadn't hit the Enter key yet to process.

The APIs were a bit complicated/confusing the first time I used them. But,
once I got a handle on how they worked, I was able to copy this into other
programs with no problems.

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?
