Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used for an information processing system. The present invention relates to modifying a source in a graphical program editor.

〔Overview〕

The present invention relates to a method of editing a diagrammatic program specification using a diagrammatic program editor, wherein when a part of a program text that represents a control structure of a program by managing a procedure as a structural unit is modified, a text including the modification portion is included. By providing a device for transmitting and processing only the part to the workstation that processes the program text, communication between the host computer and the workstation when modifying the schematic program specifications is performed efficiently. It is.

[Conventional technology]

Conventionally, an interactive editor for inputting or editing a program in an information processing system, when correcting a program text, temporarily saves the text in another area (buffer), and then responds to the correction on the screen. To rewrite the buffer.

On the other hand, in one form of network system that has been emphasized in recent years, data is centrally managed for centralized management of data, and creation and editing of centrally managed data are improved by another device to improve throughput in the information processing system. There is something to do with.

When a program text is edited with an editor in such a network system, when the program text is edited between a device storing the program text (host computer) and a device processing the program text (workstation). The whole program text or a continuous text portion of the program text is transmitted from the host computer to the workstation in units of one screen, stored in a buffer on the workstation side, and then edited.

[Problems to be solved by the invention]

Among the conventional methods described above, in the method of transmitting and receiving between the host computer and the workstation in units of the entire program text, even when a part of the program text is corrected, the entire program text is transferred from the host computer to the workstation. However, it is necessary to transfer the text from the workstation to the host computer again after editing the text, so that the uncorrected portion is frequently transmitted and received, and there is a problem in that the communication time is inefficient.

In the method of transmitting and receiving continuous partial texts of the program text in units of one screen, generally, the program is modified for each procedure unit which is a unit constituting a program function. Since the error generated by the error also occurs in the procedure unit, a method of correcting the error in the procedure unit has been desired.

Further, in some systems, the amount of communication is reduced by transmitting only the corrected portion to the workstation side and correcting it, but in the graphic program editor, displaying only the corrected portion is not a programmatic program for the graphic program editor. This leads to a problem that the purpose of expressing the control structure cannot be achieved.

The present invention solves such a problem. When a part of a program text expressing a control structure of a program by managing a procedure which is a constituent unit is modified, a procedure text including the modification is included. It is an object of the present invention to provide an apparatus capable of performing correction without destroying a graphic expression and reducing communication efficiency by transmitting only a part to a workstation that processes a program text.

[Means for solving the problem]

The present invention provides a diagrammatic program editing device provided between a diagrammatic program specification storage device in which diagrammatic program specifications are stored and a workstation including a diagrammatic program specification editing device for reading out the specifications and editing the program specifications. A specification reading device for reading a program specification, a specification temporary storage device for temporarily storing the schematic program specification read by the reading device, and a procedure management device for reading a procedure part from the schematic program specification and managing the procedure And a procedure selecting device for selecting one procedure for designating the input / output device of the workstation from a plurality of procedures constituting the schematic program specification, and reading a program specification corresponding to the designated procedure from the specification temporary storage device. Procedure specification for storing this read procedure on the workstation A procedure specification reading device to be provided to a storage device, and a procedure specification for merging an edited procedure edited by the schema program specification editing device and stored in the procedure specification storage device into a schema program stored in the specification temporary storage device. It is characterized by comprising a merging device, and a specification writing device that reads the merged schematic program specifications stored in the temporary specification storage device from the temporary specification storage device and stores the specifications in the schematic program specification storage device.

[Action]

The specification reading device reads the graphic program specification to be edited for correction from the graphic program specification storage device and stores it in the specification temporary storage device. When the instruction text indicating the required procedure is transmitted from the input / output device of the workstation, the procedure management device extracts the procedure management information from the previously stored schematic program specification and displays it on the input / output device.

When one procedure name is selected by the user from the displayed procedure management information, the procedure selecting device reads the procedure name and sends the procedure management text, and the procedure specification reading device reads the procedure specification corresponding to the text. The part is read from the primary specification storage and sent to the procedure specification storage of the workstation.

On the workstation side, the diagrammatic program specification editing device performs editing in response to an editing instruction from the input / output device, and sends out the edited diagrammatic program specification. The procedure specification merging apparatus receives the edited schema program specification, merges and edits the entire schema program specification stored in the specification temporary storage device, and the specification writing device reads the edited schema program specification and reads the schema program. Write to the program specification storage.

When a part of a program text that represents a control structure of a program by managing a procedure, which is a constituent unit, in a diagram as described above, is modified, only a part of the procedure text including the modified part is processed. By transmitting the data to the station for processing, the correction can be performed without breaking the graphic expression and without lowering the communication efficiency.
