Re: %lookup on a Data Structure Array

["Mark S. Waterbury" <mark.s.waterbury@xxxxxxxxxxxxx>]

Hi, again, Kurt:

There may be a way to do just what you want ...to search a 
data-structure array by a "key" field  ... by using ILE C/400 runtime 
routines qsort and bsearch (binary search), instead ofusing the RPG 
%lookup BIF ...

See:
    http://www.think400.dk/adhoc_4.htm

On that web page, page down just a little way to find the section "C 
runtime function - bsearch & qsort" ... it even includes example code 
that appears to be pretty close to what you are looking for ... *;-)*

Hope this helps,

Mark S. Waterbury

I really only wanted to whine about the lack of complete functionality of data structure arrays.  That is to say, I'm a huge fan and use data structure arrays a lot now, but it's a bummer that I can't use the binary search functionality of %lookup with them.  I was really hoping someone would say, "Oh, what you need to do to get that to work is [this]" and I would slap my head and say "D'oh!"   Unfortunately that doesn't seem to be the case in this situation.
