To add a subject, type the subject identification and name in the text boxes and click
on the Add button. To remove a subject, click on the subject in the list and then
click on the Remove button. To alter the identification or name of a subject, click on the
subject in the list then overtype and click on the Add button. Bear in mind that if the
identification of a subject is changed the program will automatically change the subject
identification wherever it occurs in the school data.
It is sometaimes advisable to have more than one class of a subject available within a
combination. To avoid ambiguity it is possible to add a numeric digit to a subject name.
For example, one could have Math1 and Math2. Note that it is only necessary to have Math
in the list of subjects. The numeric digit is added when the subject choices are added.
