To 124 can be selected to select a desired field. To cancel the selection, the user can click the button at the top of each field again.

When the rectangle selection mode is selected by the above-mentioned field selection / rectangle selection button 126, the user selects the field content data in the rectangular area desired by the user by dragging the mouse or the like as in the conventional case. Can be.

The field selection screen 118 shown in FIG. 3 is further provided with an overall selection button 128 at the top thereof, and is displayed on the screen when the user presses this button with a mouse or the like to select the overall selection mode. From among the field data 70 to 76, data having a predetermined attribute designated by an attribute selection menu described later can be selected collectively.

The field data selected in this way is transferred to the buffer device 54 by an editing operation such as copying or cutting, and is reused by other application software such as a spreadsheet and a word processor.

FIG. 5 is a diagram showing the attribute selection menu described above. In the same figure, in the attribute selection menu 130, a protection check box 132 and an unprotection check box 134 are displayed adjacently, and a normal luminance display check box 136 and a high luminance display check box 138 are displayed adjacently. Further, a logical symbol button 140 is displayed between them. In the logical symbol button 140, for example, an AND symbol is set by the first mouse click, an OR symbol is set next by the second mouse click, and the logical symbol is blank again by the third mouse click to cancel the condition. It can be configured to be set.

According to the host emulator device 40,
Since data having such a format can be transferred to the buffer device 54 by the input processing unit 55, for example, field content data selected / extracted by spreadsheet software or the like can be effectively used as it is. That is, as shown in FIG. 8, in a two-dimensional data format used in spreadsheet software, a character string is separated by delimiter data, so that a head character string 150 and a second character string 152 are placed at predetermined positions in a cell matrix 158. ,
.., The Nth character string can be easily arranged / stored.

Next, specific data processing performed by the host emulator device 40 described above will be described with reference to FIGS.
This will be described in detail based on the flowchart shown in FIG.

The host emulator 40 monitors the occurrence of an event at a predetermined cycle, and executes one of the routines shown in FIGS. 9 and 10 according to the type of the event that has occurred.

FIG. 9 shows that the host emulator device 40 receives a data string 44 from the host computer 42 and, based on the data string 44, a field selection screen 1 shown in FIG.
FIG. 18 is a flowchart showing a processing procedure when displaying No. 18. As shown in the figure, in this processing, first, the data analysis unit 56
Analyzes the data string 44 that is the received data and creates the screen buffer 60. Then, the data analysis unit 56 converts the original data of the display of the emulation screen 48 on the display device 50 based on the data sequence 44 into the screen buffer 6.
Store to 0. Then, the display device 50 displays the emulation screen 4 based on the data stored in the screen buffer 60.
8 is performed (S201). Subsequently, the input processing unit 5
5 monitors the input from the input device 52, and selects / selects the field on the field selection screen 118 shown in FIG.
It is determined which selection mode the rectangle selection 126 indicates (S202).

If the field selection / rectangle selection button 126 is set to the rectangle selection mode, the process returns to S201. On the other hand, when the field selection / rectangle selection button 126 is set to the field selection mode, the data string 4 received from the host computer 42
As long as the positions of all the attribute codes in No. 4 have not been checked (S203), the attribute codes are acquired (S204).
If the attribute code is a valid attribute (S20)
5) A button is displayed at the position of the attribute code (S)
206).

With the above processing, the host emulator apparatus 40 operates the field selection screen 11 shown in FIG.
8 can be displayed on the display device 50.

FIG. 10 shows the host emulator apparatus 4 when the user specifies desired field content data on the field selection screen 118 shown in FIG.
FIG. 9 is a flowchart showing a processing procedure in a process 0. As shown in the figure, first, the input processing unit 55 determines which input mode the input from the input device 52 is an operation input (S301). That is, the whole selection button 128
If is pressed, it is determined that the input is an operation input in the whole selection mode, and the attribute selection menu 130 shown in FIG.
The field belonging to the attribute range designated by is highlighted and the attribute code position of the field is recorded in a temporary memory (not shown) (S303).
On the other hand, when the field selection / rectangle selection button 126 is set to the fold selection mode, the fields specified by pressing the button 120 or the like in the field selection screen 118 are highlighted and the attributes of those fields are displayed. The position of the code is recorded in a temporary memory (not shown) (S302).

With the above processing, the host emulator device 40 operates the data string 4 of the field designated by the user.
4 can be recorded in a temporary memory (not shown).

FIG. 11 shows the contents of the field specified as described above in the host computer 4.
7 is a flowchart showing a processing procedure when extracting data from a data sequence 44 received from the buffer device 2 and outputting the data to a buffer device 54. As shown in FIG.
It is determined whether or not the position of the attribute code has already been recorded in the temporary memory by the processing shown in the flowchart (S401). If the position of the attribute code is already recorded in a temporary memory (not shown), a temporary memory for editing processing is newly prepared (S402). Further, the input processing unit 55 sequentially stores each field content data in the temporary memory prepared in S402 until the processing for all the attribute code positions recorded in the temporary memory is completed (S403) (S40).
6). At this time, if it is the first field, the character string is copied as it is to the temporary memory prepared in S402 (S406), while if it is the second field or later, the delimiter data setting shown in FIG. The delimiter data specified in the menu 142 is copied to the temporary memory first (S405), and then the field content data is copied to the temporary memory (S40).
6).

Next, the input processing section 55 determines whether the field content data specified by the input device 52 is a copy target or a cut target (S407).
If a cut has been selected, those character strings are deleted from the screen buffer 60 (S408). On the other hand, if it is determined that the operation input by the input device 52 is to instruct copying, the process returns to S403 and the same processing is repeated. In this way, if the above processing is completed for all the attribute code positions recorded in the temporary memory by the processing shown in the flowchart of FIG. 10 (S403),
The contents of the temporary memory prepared in S402 are copied to the buffer device 54, and the temporary memory prepared in S402 is released (S409).

With the above processing, the host emulator device 40 can cut the designated field content data or copy it to the buffer device 54.

FIG. 12 is a flowchart illustrating a field selection mode setting routine in the host emulator device 40. As shown in FIG.

The host emulator device 40 is capable of setting a selection mode using a menu as well as switching the current selection mode using a mode switching button. Then, in the input processing unit 55, if there is a setting operation of the selection mode by the input device 52, the selection mode is designated by the user according to whether the setting operation is the setting in the menu or the pressing of the mode switching button. (S
502, S503). Then, the display of the field selection / rectangle selection button 126 on the field selection screen 118 is updated according to the designation by the user (S504).

The host emulator device 40 described above
According to the method, the user can specify a copy or cut target in units of fields, whereby the target field contents data can be transferred to the buffer device 54 more quickly than in the conventional method of specifying a rectangular area. be able to.

Embodiment 2 Next, a procedure in which the APP 66, which is a user application, acquires field content data specified via the API 64 of FIG. 1 will be described. In this procedure, a number is defined in advance in the attribute code on the emulation screen 48 as shown in FIG. Here, numbers are assigned in ascending order from the upper left of the emulation screen 48. Then, in the host emulator device 40 according to the present embodiment, APP6
6 specifies the necessary field content data using this number and specifies the address in the user memory where the specified field content data is to be stored.
The input processing unit 55 stores the field content data desired by the APP 66 at the specified address via the API 64. Thereby, not only the host emulator device 40 but also the host emulator device 4
Also, other application software operating on the information processing apparatus constituting 0 can easily acquire and use necessary field content data.

In particular, according to the present embodiment, the field content data is specified by the number, so that even if the layout of the emulation screen on the host computer side is changed, the order of each field is changed. The same field content data as before the layout change can be continuously exchanged between the input processing unit 55 and the APP 66 without changing the processing procedure of the input processing unit 55 and the APP 66 unless the processing procedure is changed. Therefore, maintenance of the input processing unit 55 and the APP 66 can be facilitated.

FIG. 14 is a flowchart for explaining the processing procedure of the input processing unit 55 in the present embodiment. In the figure, when the input processing unit 55 receives, via the API 64, the number of the field content data required by the APP 66 and the address in the memory where the field content data is to be stored, the input processing unit 55 The address value n and the field value i which are variables used in the processing are initialized to 0 (S601). Here, the address value n is a counter used when scanning and searching the emulation screen 48.
The field value i is a counter used when scanning and searching the field.

The input processing unit 55 determines whether or not processing has been completed for all of the emulation screens 48 using the value of the address value n (S 602). The processing in the section 55 is terminated and the processing is returned to the APP 66.

On the other hand, if the processing has not been completed for all the emulation screens 48, it is determined whether or not the code at the position indicated by the address value n is an attribute code (S603). If it is not the attribute code, the address value n is incremented (S60).
7) Return to S602 and continue the process. When the code at the position indicated by the address value n is an attribute code,
It is determined that a new field starts from that position, and the field value i is incremented (S604).

Then, it is determined whether or not the field value i is equal to the field content data number already received from the APP 66 via the API 64, that is, the field number (S605).
Subsequent field content data is transferred to API
Write to the address already received from PP66 (S606). On the other hand, if the field value i is not equal to the field number, the address value n is incremented (S607), and the process returns to S602 and continues.

In each of the embodiments described above, the delimiter of each field data in the data string 44 is determined using the attribute code, and the desired field data is extracted. The above-described embodiment can be appropriately changed within a range not changed.

For example, instead of the attribute code for designating protection / non-protection, a color code for controlling the brightness and color of the field content data can be used.

Further, as an information processing device constituting the host emulator device, a mobile terminal device and the like can be similarly used in addition to a workstation.

[0051]

According to the present invention, the field contents data in the data string is designated by the designation input means, and the designated field contents data is extracted by the data extracting means based on the delimiter information of the field data such as the attribute code. Thus, the user can easily and quickly obtain necessary field content data.

Further, according to the present invention, when the designation is made by the designation input means, guidance is displayed by the selection guidance display means, so that the user can easily obtain necessary field content data.

Further, according to the present invention, when a user or the like inputs sequence information, field content data corresponding to the sequence information is extracted. Therefore, there is a slight change in the data sequence transmitted from the host computer. In this case, the user can continue to extract desired field content data.

Further, according to the present invention, when a user or the like inputs attribute range information, field content data of an attribute belonging to the attribute range is extracted. Can be obtained.
