In reports the activities/assignments are ordered by date and then by their
name.  If you have several activities entered in for one date and you wish to
control the ordering you then must use the name of the activity to specify
the correct order.

For example:

01/23/99 Worm Composition
01/23/99 Worm Diagram
01/23/99 Worm Reading

can be reordered on reports by putting a two digit number in front of each
activity as follows:

01/23/99 01 Worm Composition
01/23/99 02 Worm Reading
01/23/99 03 Worm Diagram
