Step 1 (empty database)
Step 2 create the records A,B,C (category 1) and A1, B1, C1 (category 2).
Step 3 Call DmInsertionSort
Step 4 Examine Records:
A
B
C
A1
B1
C1
Sorted Correctly (Sorted by Category, then Value).
Step 5 - Change B1 to B2...ChangeRecord calles DmFindSortPosition for
the new Record B2. I expect that this routine should return 5 (C1) so I
can insert the record after before C1 (Insert into position 4=(5-1) by
changing the position of the record 4 to record 4 (B1 changes to B2 but
should remain in the same position)). However, the function returns 2.
The only thing I can figure is that it's the second position in the
category, So, the "Insert into Position" isn't working.
Either this function isn't returning the correct value, or I'm not using
it correctly...I don't know which is the case. The normal inserts (into
position) don't work either. But sorting does work.
