Re: SORT API results

Booth,

My thought was to encapsulate this code into an external procedure to be
utilized generically for all our subfile programs on the system (so I did
not have to re-define the array into every program.) Since QLGSORT stayed
active for the job, that made since for this application.

After reading other feedback on the sort() method, I'm really starting to
think that Scott's suggestion to use that method may be more purdent in this
application.

Thank you for all your help.

If the purpose is to sort the subfile, which has a limit of 9,999 items,
it may be easier and perform faster if the subfile data is entered into
an array, and sorted with sorta. Then the subfile can be easily loaded
from the array. Just a thought.

Thanks for the feedback Scott. I was following some documentation I found

on

another site to implement the QLGSORT API, but was unable to get it to

work

outside of their example. I think I'll take your advise and use the

sort()

method.

The APIs work when used correctly, therefore I'd say you're using them
incorrectly. That's about as much information as I can provide based on
the amount of detail you've provided. Obviously, I can't tell you what
you've coded wrong unless I can see the code.

However, I have some suggestions:

a) When I've used QLGSORT to sort a subfile, I did not need to use
QLGSRTIO. I did it purely with QLGSORT. I'm curious as to why you're
using QLGSRTIO?

b) I strongly recommend against using QLGSORT. There are much easier,
and also better performing ways to sort data. the SORTA RPG op-code is
one. The qsort() API is another. My benchmarks have shown those two
methods to be MUCH faster than the other alternatives (QLGSORT, data
queues, user index, etc, were much slower.)

the

QLGSRTIO API is returning garbage for results. Neither API is returning

an

error.

Any insight would be very helpful.
