RE: Ascend on Overlay Subfield

Thanks for the answer, actually what I'm trying  to do is store some

files into dynamic arrays, ... and I want a binary search for better
performance.

In that case leave it set up as you have it.  Load the file by reading it
_without_ specifying that it is a keyed file (that will maximize buffering)
and then use SORTA against the KeyEJr array.  It will "drag" the other
fields along with it into sequence.  The you can %lookup against KeyEJr and
it will do what you want.

If the file gets too big for an RPG array then use qsort and bsearch
instead.

You might also consider loading the file into a User Space so that it only
needs loading once and can be shared between multiple jobs.
