2.1 User Interface Overview
When the user initially invokes the scheduler tool, the screen appears as shown in Figures 1.1 and 1.2. The initial display consists of a window and toolbar: the window is empty with a menu bar on the top and the toolbar consists of links to the databases.

The ‘File’ menu contains typical commands for manipulating data files and performing other system-level functions. ‘File New’ opens a blank schedule in a new display window. ‘File Open’ opens an existing schedule from a previously saved file, displaying in the current display window or a new window as selected by the user. ‘File Close’ closes the currently active schedule, offering to save if it has been modified since opening. (The currently active schedule is the one on which the user has most recently performed a command.) ‘File Close All’ closes all open schedules, offering to save any that have been modified. ‘File Save’ saves the currently active schedule on the file from which it was open, or on a new file if it was created from a new display. ‘File Save As’ allows the current schedule to be saved on a different file from which it was opened or most recently saved upon. ‘File Save All’ saves all currently open schedules. ‘File Print’ prints the contents of the currently active display window in a form suitable for output to a printing device capable of displaying text and graphics. ‘File Exit’ exits the scheduler tool.
The ‘Edit’ menu contains commands for manipulating schedule data during editing. ‘Edit Undo’ undoes the most recently completed editing commands. Repeated successive invocations of ‘Undo’ will undo successively earlier commands. ‘Edit Redo’ redoes the most recently undone commands. Repeated successive invocations of ‘Redo’ will redo the series of undone commands in reverse order. ‘Edit Repeat’ displays a dialog that allows the most recently invoked command to be repeated one or more times. ‘Edit Cut’ removes and copies the currently selected datum in the currently selected display. ‘Edit Copy’ copies the currently selected datum without removing it. ‘Edit Paste’ inserts the most recently cut or copied datum at the currently selected edit point in the current display. ‘Edit Select All’ selects all editable data in the current display. ‘Edit Find’ performs a search for a given text string. The search is performed in all open calendars; successive invocations of search with an unchanged search string searches for further occurrences of the string until all occurrences are found. ‘Edit Command’ allows the user to enter any scheduler tool command in textual form, including sequences of commands to form scripts.
