In the desktop environment in the graphical user interface environment on this display screen, various processings of the application program main unit 31 will be executed.

The program control device according to one embodiment of the present invention is started and executed as one of the application program main body 31 here, for example. For example, the program interpretation processing unit 11, the program activation control unit 14, and the like of the components of the apparatus shown in FIG. 1 are activated and executed as one of the application program main body units 31, respectively.

FIG. 4 shows U in the program start control unit.
9 is a flowchart illustrating a start-up process of a NIX program. Next, with reference to FIG. 4, the processing of the UNIX start command in the simple language program will be described. When the simplified language program is started, the program interpretation processing unit (11: FIG. 1) parses the commands of the simplified language program, and the processing of each operation designated by each command of the simplified language program is performed by the program interpretation processing. The department generates event information in the desktop environment and the process proceeds. And regarding the processing of the UNIX start command in the simple language program,
The processing is executed by the program activation control unit (14: FIG. 1).

When the program activation control unit starts the UNIX program activation process, first, in step 41, it is determined whether or not a desktop file is designated as the standard output of the UNIX program to be activated in the UNIX activation command. To do. When a desktop file is designated as the standard output, in the next step 42, the started UNIX program writes the data to the standard output and standard error output, and then fetches the data as internal data into the internal buffer. . Next, in step 43, the data in the device buffer is transferred to the buffer on the desktop environment side.

Next, in step 44, it is judged whether or not the code conversion of the transferred data is necessary. If the code conversion of the transferred data is necessary, the following step 4 is executed.
In step 5, processing for converting into a code that can be interpreted in the desktop environment is performed. If the code conversion of the transferred data is not necessary, the code may be left as it is, so the process proceeds to the next step 46, and in step 46, a document icon is created with a designated name on the desktop and is output.

On the other hand, the first step 41 when the processing is started
In the UNIX start command, the U to be started
If the desktop file is not designated as the standard output of the UNIX program, the process proceeds to step 47, and the standard output of the UNIX program to be started is UN.
It is determined whether or not the IX file is designated. If it is determined in step 47 that the UNIX file is specified as the standard output of the UNIX program, the specified U file is selected in step 48.
The UNIX file is specified as the writing destination of the standard output and the standard error output when the UNIX program is started. As a result, the process in which the UNIX program is activated is performed.

Further, in the judgment of step 41, it is not judged that the desktop file is designated as the standard output of the UNIX program to be started, and also in the judgment of the next step 47, it is judged as the standard output of the UNIX program to be started. If it is not determined that the UNIX file is designated, the standard output is not assigned and the process ends.

Thus, in the desktop environment,
When the UNIX program is started by the command of the simple language program prepared in the desktop environment, the output information of the output result output from the started UNIX program by specifying the parameters of the UNIX start command of the simple language program The error information and the like can be output by creating an icon on the desktop or by creating a file on the UNIX file system.

Next, in the simple language program, UNI
An operation example of parameter setting of the X program start command will be described. FIG. 5 is a diagram illustrating an operation example when an icon on the desktop is specified as a parameter of the output destination of the UNIX program start command. In FIG. 5, 50 is a display screen, 51 is an application window, 52 is a button of an interface component, 53
Is a sub-window displaying the button attributes, 54 is the program body of the simplified language program incorporated in the button, 55 is an output document icon created as a standard output destination, and 56 is a standard error output destination. Each of the designated and created error document icons is shown.

Here, as shown in FIG. 5, an application window 51 of an application program executed in the desktop environment is opened on the display screen 50 which is the desktop environment, and the application window 51 includes , The interface component button 52 is displayed. A simple language program is incorporated in the button 52 of the interface component as its attribute, and the simple language program incorporated in the button 52 of the interface component is displayed by opening a subwindow 53 displaying the button attribute. . The sub window 53 also serves as a program editor when the simple language program is incorporated into the button 52 as it is and the program is edited. As a simple language program that opens this sub-window 53 and is embedded in the button 52, for example, the file of the icon of the output destination is specified in the program body 54, and UNIX
Set the start command to start the program.

UNI set in the program body 54
The start command for starting the X program is, for example, "C
ALL UNIX ["OUT-file", "ERR-fil
e ", ...]" is set, and as the parameters of the start command, the standard output file name of the UNIX program that executes the start is "OUT-file", and the standard error output file name is "ERR-file". "," Is specified in the simple language program on the desktop environment side. As a result, the output result obtained from the started UNIX program is the icon file (icon 55, icon 5) having the name set by the parameter of the start command.
6) As a display screen 50 of the desktop environment
Created on top, the user can immediately check the contents.

FIG. 6 is a view for explaining an operation example when a file of the UNIX file system is designated as a parameter of the output destination of the UNIX program start command. In FIG. 6, reference numeral 60 is a display screen, 61 is an application window, 62 is a button of an interface component, and 63 is a subwindow for displaying button attributes. Reference numeral 64 is a program body of a simple language program incorporated in the button. As in the previous case,
An application window 61 of an application program executed in this desktop environment is opened on the display screen 60 which is the desktop environment.
, A button 62 of the interface component is displayed.

A simple language program is incorporated in the button 62 of the interface component as its attribute,
The contents of the simple language program incorporated in the button 62 are displayed by opening a subwindow 63 that displays the button attributes. The sub-window 63 also functions as a program editor when a simple language program is incorporated in the button 62 and the program is edited. This sub window 63 is opened, and as a simple language program to be incorporated in the button 62, in the program body 64, for example,
A UNIX program start-up command that specifies a UNIX file system file as an output destination parameter is set.

In this case, the UNIX start command for starting the UNIX program specifies a file on the UNIX file system as a standard output and a standard error output of the output destination of the UNIX program as a parameter of the command. I want the standard output and standard error output to be written out. Since the directory and file name are already known, the UNIX to be set in the program body 64
As a start command for starting the program, for example, "CALL UNIX [" /rhome/imura/temp/out.fi
Set le ”,“ /rhome/imura/temp/err.file ”,…]”. As a result, when the UNIX program is started, the UNIX file system is specified in the file specified as the output destination parameter of the start command.
The standard output and standard error output of the program are written and the file is immediately available.

FIG. 7 shows a case where the output from the UNIX program is output by creating an icon on the desktop.
It is a figure explaining an example of a NX program starting command. As shown in the upper part of FIG. 7, the UNIX program start-up command 71 has a command name “CALL UNIX” indicating that it is a start-up command, and the program name of the UNIX program to be started “/ home / imura /” as its parameter. work / prog ", the icon name" input document "of the file specified as standard input, the icon name" output document "of the file specified as standard output, and the icon name" error document "of the file specified as standard error output And the machine name "benten" of the workstation that executes this startup command is set. By executing this startup command by the processing of the simple language program in the desktop environment 72, the started UNIX program “/ home / imura / work / prog” is displayed as the icon name “input” as shown in the lower part of FIG. documents"
The data of the file 73 is read as an input, the program processing is performed, and the file data of the output result (standard output, standard error output) is used as the file 74 of the icon name "output document" and the icon name "error document".
Is output as the file 75.

FIG. 8 is a diagram for explaining an example of a UNIX program start command when the output from the UNIX program is output as a file of the UNIX file system. In this case, as shown in the upper part of FIG. 8, the UNIX program start command 81 has a command name “CALLUN” indicating that it is a start command.
UNI "and the UNI to start as its parameter
Program name of X program “/ home / imura / work / pro
g ”, the file name of the file specified as standard input“ /home/imura/work/in.txt ”, and the file name of the file specified as standard output“ /home/imura/work/out.tx
t ”, the file name“ /home/imura/work/err.txt ”of the file specified as the standard error output, and the machine name“ bente of the workstation that executes this startup command.
n "is set. By executing this start command by the processing of the simple language program in the desktop environment, the started UNIX program" / home / imura / work / "is displayed as shown in the lower part of FIG. prog ”is U
In the file system of the NIX system 82, the data of the file 83 with the file name "/home/imura/work/in.txt" is read as an input and the program processing is performed.
The file data of the output result (standard output, standard error output) is used as the file 84 of the file name "/home/imura/work/out.txt", and the file name "/ home / imura /
Output as a file 85 of "work / err.txt".

As described above, according to the program control apparatus of the present embodiment, when the UNIX program is started by using the command of the simple language program prepared in the desktop environment, it is obtained from the started UNIX program. The standard output and standard error output files can be specified by specifying the command parameters. If you want to get the icon file on the desktop, simply specify the name of the icon file you want to create on the desktop. When the UNIX program is actually executed, the program control device here reads the data from the standard output and standard error output of the UNIX program directly executed, takes in the data as internal data, and the simplified language program side Creates an icon file on the desktop with the data imported internally using the name specified in.
As a result, the user side can immediately confirm the contents.

The same applies when a certain file on the UNIX file system is designated as the standard output and standard error output from the UNIX program. In this case, the directory and file name for which you want to write the standard output and standard error output are already known, so specify the directory and file name directly on the simple language program side. When the UNIX program is started, the standard output and standard error output are written to the directory and file of the UNIX file system designated as the write destination of the standard output and standard error output on the simple language program side.

[0040]

As described above, according to the program control device of the present invention, when a UNIX program is started up in a desktop environment via a simple language program prepared in the desktop environment, As a destination of the output result (standard output) and error information (standard error output) from the UNIX program, an icon file on the desktop is created and output according to an instruction from the side of the simple language program, or UN
It is possible to start by designating whether to create and output a file on the IX file system. Therefore, the output data receiving processing unit and the simplified language program can be simplified, and the processing efficiency of the program is improved. In addition, when the icon is created and output, the user can immediately check the output result, error information and the like.
