Only the screen letter is needed to move to another screen, but once you get there, fields required for that screen will be highlighted. You can move between screens without returning to the main menu just by entering the screen letter. If you enter a name which has more than one match, the name search screen will come up and you can select the student you want. If you enter less than 9 characters for the name, make sure the remainder of the field is blank. Student screens all display the retrieved student's name, grad-year and status in the upper right.
Course screens all display the retrieved course's title in the upper right.
The Williams convention is a term in a YYS format where YY is the academic year and S is the semester.
