Re: OVERLAY in a DS having LikeDS and being based on a pointer

Here is part of the readme for my dynamically sort data. The important
thing is that utility supports dates, times, timestamps and negative
numbers.

XVSRTQ is a service program written in RPG/ILE and uses the QSORT API to
sort the data. QSORT is probably the fastest API available to sort data.



XVSRTQ is designed to be used anytime that you need to dynamically sort
data. The most common application is to sort data in a subfile but can be
used to sort anything dynamically..



For example, the user presses a function key over a field, your program
determines which field they are requesting to sort on. Each time it is
done, you might have a different key. You might even provide support for
multiple keys.



XVSRTQ supports single to multiple keys and sorts correctly for numeric
fields with precision, decimals and negative numbers. It, also, supports
dates, time, timestamps and alpha, of course. Special code is required to
sort negative numbers correctly and XVSRTQ handles all that automatically.
