The menu display means 2 and the command execution means 3 are realized by a CPU and a program for controlling the operation of the CPU (a so-called menu program). The menu program is provided by being recorded on a recording medium such as a semiconductor memory or a magnetic disk.

FIG. 2 shows a first format of the menu definition file 1 in the present embodiment.

Referring to FIG. 2, a line starting with "INI" describes an execution command to be executed before the menu screen is displayed. The description of the title of the menu screen is made in the line “T”. The row of “F” describes a frame (a frame that surrounds buttons for grouping). The button “C” describes a button. If there are a plurality of buttons, a plurality of "C" lines are described.

Display conditions are described for "F" and "C". If the display conditions are false, these items are not displayed.

For "C", an execution condition is described. That is, when the button is pressed, the execution condition of the corresponding “C” row is determined, and when true, the execution command is executed. If the line following "C" is "-", the execution condition of that line is checked, and if true, the execution command is executed. The display condition / execution condition description method allows an environment variable to be specified and the presence or absence of a file to be determined in order to obtain information specific to an operating computer. In addition to the execution program name,
Specify "*" to specify another menu definition file name. In this case, a menu screen is displayed according to the menu definition file. When a numeral is described by designating "&", the user can return to the menu screen of a higher hierarchy by the numeral and catch it. The menu program is prepared so that the menu screen can be displayed according to these rules.

Next, the operation of this embodiment will be described with reference to FIG.
This will be described with reference to FIGS.

FIG. 3 is a flowchart showing the operation of the menu display means 2.

Referring to FIG. 3, first, the menu display means 2 reads the menu definition file 1 of the main menu (step 31), and performs processing line by line.

If the read line is the "INI" line, the menu display means 2 determines the corresponding execution condition (step 32), and if true, executes the corresponding command (step 33).

If the read line is a line of "T", "F", or "C", the menu display means 2 determines the corresponding display condition (step 34). A menu item is displayed (step 35).

Further, the menu display means 2 determines whether or not reading of all lines has been completed (step 3).
6) When all the rows have been read, an event is waited.

FIG. 4 is a flowchart showing the operation of the command execution means 3.

Referring to FIG. 4, the command execution means 3 is activated by the event that the command button is pressed, and determines the execution condition of the corresponding "C" line (step 41).

Here, if the execution condition is true, the command execution means 3 further determines whether or not the execution command is a menu display instruction (step 42). here,
If "*" or "&", which is another menu screen display instruction, is specified for the execution button, the menu display means 2
An instruction to display the menu screen again using the corresponding menu definition file is issued (step 43). On the other hand, if the instruction is not another menu screen display instruction, the designated execution command is executed (step 44). Further, it is determined whether or not there is a continuation line (step 45). If the next line is a “-” line, the process returns to step 41 and the same processing is performed on that line.

With the above, the processing according to the embodiment of the present invention ends.

FIG. 5 shows a second format of the menu definition file 1 in the present embodiment.

The format shown in FIG. 5 is the first format shown in FIG.
The definition items are increased compared to the format.
For example, the presence / absence of a boundary line and the background color can be specified, the type of figure to be displayed can be specified as Shape, and the display condition cannot be displayed if the display condition is false by specifying “CN”. Instead, it can be displayed in an unselectable state.
As long as the menu program can be displayed in accordance with those definitions, the definition of the format of the menu definition file 1 can be determined in a manner desired.

In the embodiment of the present invention, the display conditions and the execution conditions can be set in the menu definition file, so that the display contents of the menu screen and the execution contents of the program based on the menu items can be changed depending on the conditions. It has the effect of being able to do it.

Also, by including the menu display command in the command stored in the menu definition file, there is an effect that the switching of the hierarchical menu screen can be performed efficiently.

Next, an embodiment of the present invention will be described in detail with reference to FIGS. This embodiment is an example in which the first format among the formats of the menu definition file 1 described above is used.

FIG. 6 shows an example of a menu screen displayed according to this embodiment. In FIG. 6, “Graph menu” corresponds to a title. "Basic graph",
The place where "other graph menu" is written corresponds to the frame. Other square frames are command buttons.

FIG. 7 shows an example of a menu definition file 1 created to create a menu screen as shown in FIG. For example, the menu display unit 2 displays the main menu using the menu definition file 1 corresponding to the main menu.

The menu definition file 1 shown in FIG. 7 is created according to the format shown in FIG.

It should be noted that, among the display condition items, "%" gives an instruction to take in environment variables. In the execution condition, “EXIST” determines whether a file exists.
“ELSE” means the opposite of the truth of the immediately preceding execution condition.

Next, the operation of this embodiment will be described with reference to FIGS.

When the menu definition file 1 shown in FIG. 7 is read, the menu display means 2 performs line by line processing. By reading the line "T" in the menu definition file 1, the menu display means 2 draws the title "Graph Menu" as specified as black, Gothic. In the following, frames and commands are also displayed in the specified colors and positions.

% FLG = 1 is specified in the display condition of the sixth line of the menu definition file 1. For example, one computer may be used by many operators, and one may not want to display the other graph menus unusable. In this case, if the environment variable FLG is set to a value other than 1 only for that computer, the display condition becomes false, so that the corresponding menu item can not be displayed.

When the "return" button shown in the twelfth line of the menu definition file 1 is pressed, the execution command is "&
1 ", indicating that the display returns to the menu one level higher. The menu program rereads the menu definition file one level higher and displays the menu screen.
The execution command marked with “*” also reads the specified menu definition file and displays the menu screen.

When the "end" button shown in the bottom line of the menu definition file 1 is pressed, the command execution means 3
Determines the execution condition of the corresponding command button row.
In this case, since "EXIST FLG" is present, the existence of a file named FLG is checked. Execute a program called EXE. Then the next line is "-", so
This line is also an execution target, and if the execution condition “ELSE” is true, END. Execute EXE. Thus, F
It is possible to change the execution program when the end button is pressed depending on whether there is a file named LG.
