First some history.
There is nothing magical about the alphabetic folders in FreePM.
The ONLY reason they are there is that when I was doing some of
the original testing of folders (before BTree Folders) I found
that when you reached around 7000 - 8000 items in a folder it
took awhile to render the page. So the solution was to break the
numbers down into more manageable segments. With 26 characters
and say 5000 records / character I could more easily manipulate
130,000 records (okay I know that there will be more A's, L's &
M's than Q's, X's and Z's). That's why it's not magical, it was
just someway to break up the groups. It could just (almost) as
easily be done by grouping them in the order they are created.
Anyway using BTree Folders I have put 25,000 + objects in a
folder w/o problems.
The objects are really tracked by their ID which is an
EMR-xxxxxxxxx (where xxxxxxxx is a number generated from the
time). The ID problem you have is with the small piece of code
that I use to decide which folder to put it in from the last
name. All we have to do is remap those characters to 'a' folder.

I'm not sure I understand this question. I think you are asking
what I just said above?

I really did have a good reason for using the drug names as id's.

But the plan calls for implementation of the Multum drug database
by March 25, so this is a moot point anyway. We will be using
the Multum number for id's at that point.
