Description
Background of the Invention
1. Field of the Invention
The present invention relates to a method of and an apparatus for displaying a list of files, selecting one of the files, and executing a program with simple operations.
2. Description of the Related Art
Workstations and personal computers widely employ UNIX (a trade name of Unix System Laboratories, Inc.) and MS-DOS (a trade name of Microsoft Corp.) as an operating system. These operating systems employ a hierarchical file system using special files called directories to control or access many usual files.
Software called a file manager displays a list of files available to a user. The file manager displays a hierarchical structure of directories and displays a list of files, which are accessed by one of the directories selected by the user.
There is a method to easily start a program. This method registers program execution data for each program and executes the program according to the registered program execution data. This method is employed by, for example, a program manager of Microsoft Windows (a trade name of Microsoft Corp.). This program manager includes a file name of the program execution data so that a program to be executed may handle or execute the file name. The program execution data may include a specific part of the file name such as an extension.
A hierarchy of directories of the conventional file system may have an optional depth. As the depth becomes deeper, it becomes more difficult to find a directory that controls or accesses a required file.
Although the conventional method of executing a program, according to registered program execution data, is capable of specifying a file to be handled or executed by the program, the conventional method can not dynamically change the file. Accordingly, it is necessary to register new file data to permit the program to handle another file.
The conventional method of executing a program according to a specific part of file names includes only one file extension in the program execution data.
Summary of the Invention
An object of the present invention is to easily display a list of file names according to an optional title without specifying a directory.
Another object of the present invention is to provide a program execution method that allows an executable program to be optionally combined with a file to be handled or executed by the program.
Still another object of the present invention is to provide a method of displaying items and relationships among the items in a window on a display, to visually guide a user to procedures of selecting an executable program and a file to be handled or executed by the program.
Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the figures thereof.

(5) Executing a Program on an Item
Executing a program according to a registered work item will be explained next with reference to FIGS. 24 and 25. FIG. 24 is a flowchart showing steps carried out by the processing unit 21 of FIG. 2, and FIG. 25 shows the operation screen 71.
Step F11 of FIG. 24 displays items in the window according to the display data 35 of every item records 34.sub.1 -34.sub.N in the item table 30, i.e., the work item table 170. In the item window 112 of FIG. 25, each shape 125 representing a work item is displayed according to the coordinates width, height, and attribute contained in the work item display data 171.
Step F12 displays relationships among the items according to the display data 42 stored in the item relationship table 40. In the window 112 of FIG. 25, the work item relationships are displayed as arrow marks 126.
According to the item selection instruction 11 provided by a user, step F13 finds the coordinates of a mouse pointer and specifies a corresponding one of the item records 34.sub.1 -34.sub.N in the item table 30.
Step F14 determines whether or not the item record 34.sub.1, for example, has been specified. If YES, step F15 is carried out, and if NO, the flow returns to the step F13. The determination of the step F14 is carried out according to whether or not the left button of the mouse has been pushed in the work item display shape. If the item record 34.sub.1 has been specified, the corresponding shape is inverted on the display. In FIG. 25, the item CREATE PROGRAM is selected and inverted.
Step F15 displays a list of file names in the window according to the file list data 36 of the specified item record 34.sub.1. In FIG. 25, the work item CREATE PROGRAM has been selected, the number of the file list is read out of the file list link data 172 of the work item, the title LIST OF SOURCE FILES in the title list window 73 is inverted according to the file list data 36, and a list of corresponding file names is displayed in the file list window 74.
According to the file selection instruction 12 provided by the user, step F16 extracts one of the file names. In FIG. 25, a file PRG.COB is selected and inverted in the file list window 74.
Step F17 combines the selected file name and the program execution data 37 of the specified item record and executes a program. In this example, the file name PRG.COB in a directory C:.backslash.MASTER.backslash.TEST.backslash.SOURCE is specified as an execution parameter of a program having a file name of NOTEPAD.EXE in a directory C:.backslash.WINDOWS, and the program is executed. The execution of the program is requested to the operating system in the following format:
C:.backslash.WINDOWS.backslash.NOTEPAD.EXE C:.backslash.MASTER.backslash.TEST.backslash.SOURCE.backslash.PRG.COB
FIGS. 26A and 26B show the file list table 3, in which FIG. 26A shows the structure of the table, and FIG. 26B shows the table with registered data. The title date 32 include displaying order numbers and titles. The file list data 33 include directory names and file extensions. If the LIST OF SOURCE FILES is selected, files controlled under a directory of C:.backslash.MASTER.backslash.TEST.backslash.SOURCE and having an extension of COB are all displayed. These files are retrievable as C:.backslash.MASTER.backslash.TEST.backslash.SOURCE.backslash.*.COB, with a wild card. The file list data 33 may include other listing conditions such as file attributes.
FIGS. 27A and 27B show the menu item table 160, in which FIG. 27A shows the structure of the table and FIG. 27B shows the table with registered data. The menu item display data 161 include displaying order numbers, menu items, alphabetic mnemonics, katakana mnemonics, etc. The executable program data 162 include file names of executable programs.
FIGS. 28A and 28B show the work item table 170, in which FIG. 28A shows the structure of the table and FIG. 28B shows the table with registered data. In the table 170, the work item display data 171 include the names, coordinates, widths, heights, etc., of work items. These data correspond to the display data 35 of the item records 34.sub.1 -34.sub.N and the display data 42 of the item relationship records 41.sub.1 -41.sub.N of FIG. 2. The file list link data 172 include the displaying order numbers of the file list records. The data 172 and corresponding entries in the file list table 3 of FIGS. 26A and 26B correspond to the file list data 36 of FIG. 2. The executable program data 173 include file names of executable programs. The data 173 correspond to the program execution data 37 of FIG. 2.
As explained above, a user selects one of the titles displayed in a first window, and then the present invention displays a list of file names in a second window according to file listing conditions corresponding to the selected title. Accordingly, the present invention allows the user to easily retrieve required file names and select one of the files.
The first window displays items and relationships among the items. When the user selects one of the items, the present invention specifies a file list record and program execution data corresponding to the selected item and displays a list of file names in the second window according to listing conditions of the specified file list record. If the user selects one of the file names in the second window, the present invention combines the file name with the program execution data and executes the program. Accordingly, the present invention enables the user to execute a program and specify a file to be handled by the program. The present invention displays even the relationships among the items, so that the user easily executes programs according to work sequences.
While the invention has been illustrated and described in detail and the drawings and foregoing description, it will be recognized that many changes and modifications will occur to those skilled in the art. It is therefore intended, by the appended claims to cover any such changes and modifications as fall within the true spirit and scope of the invention.
