The course and unit level

In the X based version these are both in the main window

In the text based version: When you have selected a particular course, the menu shown in figure should now be displayed on the screen.

This menu is identical whether it is obtained from the system level of Ceilidh using the sc command, or by entering Ceilidh with a -c argument.

We are now in a chosen course. The various possible commands have the following significance.

lu

(text only - list unit :the units are automatically listed in X version once the course has been selected)

Each course is divided into a number of units, rather like the chapters of a book. This option lists the name of each unit, giving you a brief outline of the course as a whole. Typical output might be

          Units in course pr1
            Unit 1: Background
            Unit 2: Elementary programming
            Unit 3: Conditionals
            Unit 4: Loops
            Unit 5: Functions
            Unit 6: Miscellany
            Unit 7: Arrays and structures
            Unit 8: File input and output
            Unit 9: Pointers

lux

(text only) This command lists all units and exercises within these units.

csum

(Course Summary button) If the teacher remembers to keep the information up-to-date, this command gives you a summary of the timetable for your course, with

details of the courseworks to be set, and the hand-in dates for each one.

state

(text only - See message of the day MOTD) As a course progresses exercises are opened, made late and then closed. This command gives a summary of the state of each exercise.

Select Unit Button (su)

This command enables you to select a chosen unit of the course. The menu remains the same, apart from the currently selected unit number which is included at the top of the menu. Commands below which relate to a specific unit use the currently selected unit number.

Unit Summary Button (usum)

This will list a brief summary of the currently selected unit, usually at the level of section headings in the notes.

View Notes Button (vn)

This command (view notes) allows you to view on-line the notes for the current unit of the course.

q

(text only) This is the command to quit the system. If you entered Ceilidh at the course level with a command such as

          ceilidh -c pr1

the quit will return you to your shell. If you entered the course level from the system level using first

          ceilidh

and then

          sc pr1

for example, the quit returns you to the system level of Ceilidh, and you will need another quit to return to your shell.

Your current unit and exercise will be noted, so that when you re-enter Ceilidh, you will default to the same unit and exercise as when you left. If you wish to quit without saving your current state, use q!

instead.

Make Comment Button (co)

At many points in the Ceilidh system, the system allows you to make comments to the course teacher. Comments are always welcome. Comments may be a request for help ("What do you mean by .... in this week's question?"), a criticism of the system ("I think the mark it gave me was not fair"), or an apology for the late hand-in of work ("Sorry but I had an examination ..."). Please feel free to use this facility; the teacher will try to answer most queries. The comments are sent using email to the teacher in charge of the course.

Change Printer (clp)

- may not work !! Whenever you use a command which involves printing some information, the computer chooses the printer which it thinks is most convenient. This is done by looking at where you are on campus. Sometimes the computer chooses the wrong printer (it cannot always tell exactly where you are on a network), so there is a facility for you to choose a particular printer by name. You will be told appropriate printer names in class.

To work on your coursework, you will need to move from the "unit" level of Ceilidh into the "exercise" level.
