For the purpose of storing the control information of the input device in the device information area.
Address area and second address area of
For TAOFF, the DATAON processing module or the input module is pointed to from the first address area, and when the READ statement is executed, the data is branched to the address indicated by the first address area, and the DATAON processing module is moved to the second area. It is configured to branch to the address of the input module indicated by the address area of.

[Industrial applications]

The present invention relates to a data processing device having a DATAON processing function for outputting input data in a FORTRAN program to a standard output device.

The FORTRAN DATA ON processing function is a function that outputs the input data read from the standard input file to a standard output device (file) such as a display or a printer without directly editing it. DATAOFF is a function that invalidates the DATAON processing function. It is desired to speed up these processes as much as possible.

[Conventional technology]

 FIG. 4 shows an example of the conventional method.

The application program 11 is a source program written in FORTRAN that is translated / combined.

Conventionally, the DATAON / DATAOFF of the input device is the DATAON flag 40 in the device information area 18 that stores the control information of the input device.
Was managed by. When DATAON flag 40 is "0", DATAO
In the FF state, when it is "1", it is in the DATA ON state.

In the initial state, the DATAON flag 40 is set to "0", and when the DATAON statement calls the DATAON service subroutine 12, DAON
The TAON service subroutine 12 sets the DATAON flag 40 to "1"
Set to. The DATAOFF service subroutine 14 operates in response to the DATAOFF statement and resets the DATAON flag 40 to "0".

When the READ statement for the input device is executed, the sequence processing module 13 calls the input module 16. After the input module 16 refers to the device information area 18 and executes the data input processing, whether the DATAON flag 40 is "0",
Determine whether it is "1". If the DATAON flag 40 is "1", the DATAON processing module 15 is called and the processing of outputting the input data to the standard output file is performed.

[Problems to be Solved by the Invention]

As shown in Fig. 4, in the conventional method, DATAON / DATAOFF
The function of was handled by the input module 16 of FORTRAN.
That is, in the case of the standard input file, the input module 16
If it is DATA ON, it is judged whether it is in the DATA ON state in
The TAON processing module 15 prepares for output, calls the output module, and outputs the data read by the input module 16.

In a normal program, the vehicle often runs in the DATAOFF state. However, according to the conventional method, even when the DATAOFF state, it is necessary to judge whether it is the DATAON state or the DATAOFF state. There was a problem that the performance deteriorated as much.

In addition, from the input module 16 to the DATAON processing module 1
Since output modules, which are other access modules, are called via 5 and it becomes difficult to adopt a hierarchical module configuration, there is a problem that processing sharing becomes complicated.

It is an object of the present invention to solve the above problems and improve the processing performance by eliminating the need to determine DATA ON / DATA OFF in the input module. It also aims to simplify the module configuration and prevent the processing from becoming complicated.

[Means for solving the problem]

 FIG. 1 shows a configuration example of the present invention.

In FIG. 1, 10 is a processor comprising a CPU and memory, 11 is an application program created by translating / combining FORTRAN programs, and 12 is DATAO that processes DATA ON statements.
N service subroutine, 13 is a sequence processing module provided as a FORTRAN library, 14 is a DATAOFF service subroutine for processing a DATAOFF statement, 15 is a DATAON processing module called in the DATAON state, 16 is an input provided as a FORTRAN library An input module for processing, 17 is an output module provided as a FORTRAN library for performing output processing, 18 is a device information area (UIA) for storing device control information, 19 is a first address area, and 20 is a second
Address area, 21 is a data input device, and 22 is an output device such as a display.

In the present invention, in the device information area 18 for storing the control information of the input device 21 to be DATAON processing target, the first address area
19 and a second address area 20 are provided.

In the initial state and the DATAOFF state, the address of the input module 16 is set in the first address area 19 and the second address area 20. In the DATA ON state, the address of the DATA ON processing module 15 is set in the first address area 19 and the address of the input module 16 is set in the second address area 20. The first address area 19 is updated by the DATAON service subroutine 12 and the DATAOFF service subroutine 14.

When the arrangement processing module 13 is called during the execution of the READ statement, the arrangement processing module 13 uses the first address area.
Branch to the address indicated by 19. As a result, in the DATA OFF state, the input module 16 is called, and in the DATA ON state, the DATA ON processing module 15 is called.

The DATAON processing module 15 obtains the address of the input module 16 from the second address area 20 and
After calling 16 and receiving the input data, the output module 17 is called next and the output module 17 is requested to output. The output module 17 outputs the input data to a predetermined output device 22.

[Action]

Arrangement processing module 13 is in the DATA ON state or DATA OFF
Since it is only necessary to call the module of the address stored in the first address area 19 of the device information area 18 unconditionally without being aware of the status, it is not necessary to judge DATA ON / DATA OFF. Further, when DATAON is set, the input module 16 and the output module 17 are called from the DATAON processing module 15, and the input module 16 and the output module 17 can be treated as modules of the same level, which simplifies the processing configuration. .

〔Example〕

FIG. 2 is an explanatory view of one embodiment of the present invention, and FIG. 3 shows a processing flow of the DATAON processing module according to one embodiment of the present invention.

For example, assume that a FORTRAN program as shown in FIG. 2 (a) is executed. The initial state is the DATA OFF state. In the READ statement of (a), the input data of A is not output because it is in the DATA OFF state. (B) DATA ON statement, DAT
In the AON state, the next READ statement (c) reads the input data into A and outputs the data to a predetermined output device. The DATAOFF statement in (d) returns to the DATAOFF state. The above control is realized as follows.

In the case of DATA OFF state, as shown in Fig. 2 (B), FORT
The head address of the input module 16 is stored in the first address area 19 and the second address area 20 of the device information area 18, which is a table used inside the RAN.

When the FORTRAN READ statement is executed in this state, the arrangement processing module 13 operates, and the arrangement processing module 13 acquires the head address of the input module 16 from the first address area 19 and makes an input request. . As a result, only data is input.

When the DATAON service subroutine 12 shown in FIG. 1 is executed, the DATAON service subroutine 12 causes the DATAON processing module 1 to display in the first address area 19 of the device information area 18.
Set the start address of 5.

That is, as shown in FIG. 2C, in the DATA ON state, the DAT is stored in the first address area 19 of the device information area 18.
The start address of the AON processing module 15 is in the state where the start address of the input module 16 is stored in the second address area 20.

When the FORTRAN READ statement is executed, the alignment processing module 13 operates, and the equal processing module 13 fetches an address from the first address area 19 and branches there. This procedure is the same as in the case of DATA OFF, but the destination of control is the DATA ON processing module 15. The DATAON processing module 15 calls the input module 16 to read the data, and then calls the output module 17 to output the data. After that, the data is arranged and the processing module
Pass to 13.

When the DATAOFF service subroutine 14 shown in FIG. 1 is executed, the DATAOFF service subroutine 14 copies the contents of the second address area 20 into the first address area 19, and the state shown in FIG. Return to.

The processing flow of the DATAON processing module 15 is as shown in FIG. The process will be described below in accordance with the processes shown in FIG.

At the time of DATAON, the DATAON processing module 15 is called. From the second address area 20 in the device information area 18 of the corresponding input device, the DATAON processing module 15
The start address of the input module 16 is taken out.

By branching to that address, the input module 16 is called and the input data is received.

Next, the standard output file that outputs the input data is
Determine if PEN has been done. If it has been opened, move to processing.

If it has not been opened, OPEN processing of the output file is executed.

The input data received from the input module 16 is transferred to the output buffer.

Invokes the output module 17 and outputs the contents of the output buffer. Then, the input data is returned to the calling sequence processing module 13, and the processing is terminated.

〔The invention's effect〕

As described above, according to the present invention, the arrangement processing module and the input module do not need to be aware of DATAON / DATAOFF, and the processing speed is increased. Also, the output module is not called directly or indirectly from the input module, the interface between modules is simplified, and the processing procedure is simplified.
