Joel Ewing's post makes several important points. Hashing would
certainly reduce the size of the key space to be searched, making your
search scheme a little less important.
Another possibility that you should consider is the use of a
binary-search tree (BST). Even without AVL balancing or the
My concern about memory was not for above the bar or even above the line, but
about real storage. I have been involved in situations where a sort that
worked fine last week, didn't work so well this week. Nothing changed in the
operating system or the sort.
What did change was a new DB2
Thanks again to all who made suggestions. We think the problem turns out to be
that one section of code is doing a wide-ranging call (that is, calls a
function that itself does a Whole Lot Of Stuff) on every iteration and
shouldn't be. This would explain the relative lack of hotspots: the extra
Hi Folks,
I just put out CBT Tape Version 485, and I discovered some errors
on the load module file, File 035. Three PL/I program load modules are
erroneously marked as being AMODE 64. They should be corrected as follows:
ASMTOZAF - should be AMODE 24
VSAMANAL - should be AMODE 31
Hi Folks,
I'll fix File 035 on the Updates page, to have the correct AMODE
for the three programs, ASMTOZAF, VSAMANAL and VSAMANDX.
I guess this will be the easiest way to get the corrected
programs. Also, the tape mapping program called SS0104 (from CBT File
266) has been fixed on

I guess my main point is when making significant changes you need to
have situational awareness. A good choice for one situation may be a
terrible choice for another.
On the question of design, I would vote for using hashing, if you have
a hashable key. It
