Abstract

PURPOSE:To facilitate the evaluation by simulating a communication processing unit so as to evaluate quickly an on-line program thereby outputting the content of a text. CONSTITUTION:An instructure data section 1 implements the processing to read one record from an instruction data file and when a record to be read is in existence, an instruction data analysis section 2 takes over the control, and when no record to be read is in existence, a text image output section 7 takes over the cotrol. The analysis section 2 discriminates an identification code in the read record to control the movement of text transmission reception. When an identification code is S, a transmission text analysis section 3 for text transmission takes over the control and when the identification code is R, a text reception section 5 for text reception takes over the cotnrol. The analysis section 3 saves the content of a request text into a memory to take reference between the request and the reply in the case of request text transmission. When a request item is 0, that is, in the case of a request text, the content of the text is saved in a storage area defined in the simulation device and a text transmission section 4 takes over the cotnrol. When the request item is 1 (reply text) or 2 (notice text), no processing is implemented and the transmission section 4 takes over the control. The transmission section 4 sends a text to an on-line program 11.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides a network system using a communication processor, in order to facilitate the development of an online program that involves sending and receiving messages.
The present invention relates to a communication processor that makes it easy to implement the transmitting and receiving functions of the communication processor using a program.

0002

[Background Art] Traditionally, when developing online programs, the technical background is that a network environment has been created, that is, a host computer and a terminal device are connected online and data can be transferred. If the communication processor that exchanges data with the host computer had been completed and a network had been constructed, it would have been possible to evaluate the communication environment without any problems.

0003

[Problem to be solved by the invention] However, in recent years, in large-scale network systems, it has become increasingly common to develop communication processors specifically for the system, and to develop new software for existing communication processors. . In that case, the development of the online program in the host computer and the software of the communication processor are done at the same time, resulting in a time delay in the evaluation of the online program that involves sending and receiving data. be.

0004

[Means for Solving the Problems] A communication processor pseudo device of the present invention is a communication processor pseudo device that includes an online program for transmitting and receiving data to and from a terminal in a host computer. a reading section, an instruction data analysis section that analyzes the contents of the instruction data to determine whether to send or receive a message, and an instruction data analysis section that analyzes the contents of the transmission message to determine whether the transmission message is a response from the online program. If it is a required message, a transmitted message analysis unit that stores the transmitted message, a message transmitting unit that sends the message to the online program, a message receiving unit that receives the message from the online program, and the received message a received message analysis unit that analyzes the received message to determine whether it is a request message from the online program, a response message, or a notification message, creates a response message to the online program, and compares it with the stored message;
It is configured with a message output section that edits received and transmitted messages and outputs a list.

EXAMPLES Next, the present invention will be explained according to examples with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and FIG. 2 is a diagram showing the configuration of this device and an online program.
FIG. 3 is an explanatory diagram showing the flow of messages, FIG. 3 is an explanatory diagram showing the record layout of the instruction data file, FIG. 4 is an explanatory diagram showing the messages, and FIG. 5 is an explanatory diagram showing the message list.

In this embodiment, an instruction data reading section 1,
It is composed of an instruction data analysis section 2, a transmitted message analysis section 3, a message transmission section 4, a message reception section 5, a received message analysis section 6, and a message output section 7.

Next, the operation of this embodiment will be explained.

The instruction data section 1 performs the process of reading one record from the instruction data file, and when there is a record to be read, transfers control to the instruction data analysis section 2, and when there is no record to be read, it outputs a message image. Control is transferred to section 7.

[0010] The instruction data analysis unit 2 determines the identification code in the read record and controls the transmission and reception of messages by this device. Explaining based on FIG. 3, when the identification code is S, control is transferred to the transmitted message analysis unit 3 for sending the message, and when the identification code is R, control is transferred to the message receiving unit 5 for receiving the message. Move.

[0011] The transmission message analysis section 3 stores the contents of the request message in a memory in order to establish a correspondence between the request and the response when transmitting the request message. Explaining based on FIG. 4, when the request classification is 0, that is, a request message, the message contents are saved in a storage area defined within the device, and control is transferred to the message transmitter 4. When the request classification is 1 (response message) or 2 (notification message), no processing is performed and control is transferred to the message transmitter 4.

[0012] The message sending unit 4 sends a message to the online program. Thereafter, control is transferred to the instruction data reading section 1 to read the next data.

The message receiving section 5 receives the message from the online program and transfers control to the received message analyzing section 6.

The received message analysis section 6 controls the operation of the apparatus by determining the request category in the received message. This will be explained based on FIG. 4. When the request classification is 0 (request message), the command name and command serial number of the received message are set in the response message to be sent, and control is transferred to the message transmitter 4. When the request classification is 1 (response message), the command name and command serial number of the received message are checked to see if the command name and command sequence number of the transmission request message stored in the transmission message analysis section 3 match. If there is a response request message, the saved message is erased from the save area. If there is no response request message, a message is output to the console display as an error message received. In either case, control is transferred to the instruction data reading section 1 and the next data is read. Control is transferred to request category 1, and data is read next. When the request classification is 2 (notification electric charge), no processing is performed, control is transferred to instruction data reading 1, and the next data is read.

The message image output unit outputs a list of images of received and transmitted messages after all processing is completed and there is no more data to read. Explaining based on FIG. 6, a serial number is assigned to each reception and transmission, and the processing is edited and outputted so that the order of processing can be understood.

[0016]

As described above, according to the present invention, by simulating the communication processing device, it is possible to eliminate the time delay in evaluating online programs. In addition, by outputting the message contents as a list,
This has the effect of making evaluation work easier.
