There are two ways to get around this problem.  If you
just want the ordering to be unsorted for input screen purposes
(ie.  just on the screens) then use method 1 described below.
If don't want the students sorted, but would rather control
the ordering of students in both the screens and reports
then use method 2 described below.

Method 1
--------

Enter a three digit number in for the homeroom or student ID 
if you are not using those fields.  Enter numbers like:

Name          Home Room or Student ID
----          -----------------------
Smith, John   010
Doe, Jane     020
Doe, John     030
etc.

Now on each input screen you can choose to sort by Students 
for alphabetical order or by Home Room / Student ID for the 
order you have specified.

Method 2
--------

Place a three digit number in front of each student name so
that when the program tries to sort alphabetically it will
acually be sorting via the ordering you have specified.

ie.
Student Name
------------
010 Smith, John
020 Smith, Jane
030 Doe, Jane
etc.

Note that with this method the numbers you assign will show up on
reports.
