[Effect]

The method of controlling transmission/reception data queue management by an online system according to the present invention attaches a pointer to an input/output queue management file, thereby making it possible to arbitrarily manage message input/output for each terminal device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the same parts as in FIG. 9 are indicated by the same reference numerals. 41 is a transmission/reception processing program, 51 is an input queue management file, 52 is an output queue management file, and 9 is a business processing file. be.

Next, the operation will be explained. First, when data is transmitted from the terminal device 1 to the host computer 10, the host computer 10 receives the data in the communication control device 2, passes it through the communication management program 3, and stores the data in the input queue management file 51 using the transmission/reception processing program 41. is input. Then, according to the user's arbitrary specifications, the data from the terminal device 1 on the input queue management file 51 is processed according to the priority schedule, that is, the input queue management file 51 performs real-time processing, remote batch processing, and local batch processing for sending and receiving data. etc., and the output queue management file 52 starts management such as starting distribution processing. In order to manage the priority schedule for data from the terminal device 1, input/output queue management files 51 and 52 shown in FIG. 2 are prepared. Its structure consists of an IJ part 11 (fixed pointer) and an IJ part 12 (fluctuating pointer). and text group 12B, and data management from the multi-terminal device 1 is facilitated by assigning pointers to each directory section. I/O queue management file 51
．． All data records within 52 are in variable length format.

In addition, the input/output queue management file 51 shown in FIG.
The job directory section 11A and station directory section 11B of 52 serve as an index list for accessing the queue management file. Further, the batch directory section 12A serves as an index book for managing a series of text groups 12B under the job directory section 11A and station directory section 11B of the queue management file.

The user can then treat a certain series of text groups 12B as one normal file. Next, the job directory record format of the input/output queue management files 51-52 shown in FIG. 3 will be explained. I/O queue management file 51.520 A job directory record is created at the first code of the queue management file by giving the job number when creating the queue management file. I/O queue management file 51゜5
Job directory record No. 2 is the highest index list of the queue management file, and indexes for the number of jobs specified at the time of creation of the input/output queue management files 51 and 52 are secured. By specifying an index number (job number) when accessing the queue management file, the user can categorize batches in the queue management file into levels. And input/output queue management file 5
1.52 job directory records are used to prioritize transaction-enabled job scheduling and to determine whether the corresponding job is automatically scheduled as a single job or as a batch job. This is used to classify scheduling methods, such as whether the schedule is initiated by an operator or not. On the other hand, the output queue management file 52 is used for prioritizing automatic distribution by Job Directory and classifying whether distribution is automatic or based on a request from a terminal device. The job entry format of the input/output queue management files 51 and 52 is the job entry format of the input/output queue management file in Figure 4 (when there is a terminal device directory) and the input/output queue management file in Figure 5. job entry format (
(when there is no terminal device directory). Also,
The terminal device directory record format of the input/output queue management file shown in FIG. 6 can be arbitrarily created for each index number (job number) when creating the queue management file. The terminal device directories and record formats of the input/output queue management files 51 and 52 in Figure 6 are for distributing batches in the queue management file to each terminal device. It becomes an index book.

In other words, the terminal device directory records in the input/output queue management files 51 and 52 are used for processing such as timing from the terminal device 1 in the output queue management file 52 and distribution processing based on a request from the terminal device 1. It is established to carry out the following. It is also used to perform high-speed extraction of batch processing for specific terminal devices.

Furthermore, the input/output queue management file 51 shown in FIG.
The 52 batch directory record format is coded for terminal data as it is imported into the queue management file. Assuming that a series of terminal device data is one file, this corresponds to a file label. The batch directory record format of the input/output queue management files 51 and 52 is used when inputting terminal device 1 data into the queue management file 77'. By adding data L(a
), searching for batch processing in the queue management file by identifier; (b), for patch processing in the input queue management file 51, scheduling the corresponding job using the identifier and arbitrary data; (C) For batch processing with the same identifier, store the time of input processing or output processing of terminal device data in the queue management file as optional data to support reprocessing. . (d) In addition, as arbitrary data, the identifier of the partner station, the telegraph telephone number, the status of batch processing, etc. can be stored to select various uses. The user information in the batch directory record format of the input/output queue management files 51 and 52 shown in FIG. 7 can be handled as arbitrary data by the user. Further, the text record format of the input/output queue management files 51 and 52 shown in FIG. 8 is a data unit for inputting and outputting terminal device data of the input/output queue management file.

〔Effect of the invention〕

As described above, according to the present invention, as a control method for queue management of transmitted and received data by the host computer during online processing between the terminal device and the host computer, the queue management file is managed with a pointer, so the terminal This has the effect that the user can arbitrarily control and manage data from the device and can quickly and easily index data from the terminal.
