Default convert long list into shorter list

If you have 5 staff with 1000 entries, looping is wasteful of resources.
Would you consider Find previous method from bottom up (Since the list has
been sorted)?

Cheers!

have a three column range holding the following data: Col1 employee name,
Col2 a date the name was entered into the table, Col3 the employee's
assignment
As the employee's assignment changes, the table is updated by adding their
name to the end of the range in Col1, entering the date the assignment
became effective in Col2, and the new assignment in Col3. When (if) any

new
assignments are entered, the entire range is sorted by Col1 (employee

name)
in ascending order. Thus, from day to day, the range will grow longer as

new
or duplicate names are entered. I have to keep the entire range for
historical tracking, but I need an additional table that holds only the

most
recent or current assignments.

The following "long" list should produce a resulting "short" list: Columns
separated with semicolon for clarity here.

LongList
Doe, John; 1/1/07; Line 1
Doe, John; 2/5/07; Line 3
Doe, John; 3/2/07; Line 4
Doe, Terry; 1/1/07; Line 2
Jun, Mary; 1/1/07; Line 4
Jun, Mary; 1/23/07; Line 7
Jun, Mary; 2/17/07; Line 3

ShortList
Doe, John; 3/2/07; Line 4
Doe, Terry; 1/1/07; Line 2
Jun, Mary; 2/17/07; Line 3

I'm thinking about looping (or moving) down the LongList row by row

looking
at each entry in Col1 comparing to the next to determine the final entry

of
the matches. Using that value, begin populating the new table. However, as

I
begin writing the looping, I don't know if I should use Next For, For each
Next, or something else.
