The rooms database must contain all of the rooms that are to be used to schedule classes. Professor's offices should not be in this list. The program does make it possible to place courses in a professor's office (which would be done with an independent study) but that is done through a different facility.
To open the room editor select Edit > Edit Rooms... from the main menu. When you do, a small window will open which contains a list of all the rooms you currently have in the rooms database.
At the top is a small toolbar with three buttons. The first is for adding a new room to the database, the second is for editing a current room and the third is for deleting a room. When you add a room an input room dialog box will appear allowing you to input the properties of the room. The first field is for a building code. The rooms will show up on many of the reports that are generated, including schedule cards, so the building code should be short. The maximum capacity should be set to the maximum number of students you will put in the room. This number is used to calculate the maximum number of students you can support in a particular course. If the room is a lab you should click the Lab check box as well.
To edit a current room either select the room and click the second toolbar button or just double-click the room. When you do, the same room dialog box will appear with the room properties loaded. Simply make the desired changes and select the OK button.
Once your rooms have been input they will show up on the room schedule interface, as shown below.
One technical note about rooms. Rooms are linked to the schedule so if you had a room, say HS 115, and for some reason that room was given to another department and you were given CH 221 instead, if you change the HS 115 room to CH 221 all of the classes that were in HS 115 will now be in CH 221. Also, if you delete a room any classes that were scheduled in that room will need to be rescheduled. That is, those classes will be removed from their room and times but not removed from the schedule.
