Abstract

PURPOSE:To improve a processing speed by collectively processing plural records by a specification from a user program at the time of inputting/outputting data. CONSTITUTION:A control block 2 is formed from the information specified by the user program 1 and whether data I/O is to be executed in each record or collectively executed in the unit of plural records in I/O method recognizing processing 3 is segmented from the control block 2. In the case of recognizing the I/O of each record, ordinary I/O processing 4 is executed. In the case of recognizing the batch execution of plural records, new I/O processing is executed, control is transferred to a magnetic disk 1/O interface 6 and data are inputted/outputted in/from an external storage device 7. Since plural records can be collectively processed, rapid data processing can be attained.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、データ処理方式、特にデータの入出力方法を
ユーザプログラムの指定によって任意に変更することが
できるデータ処理方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing method, and particularly to a data processing method in which a data input/output method can be arbitrarily changed by designation of a user program.

〔従来の技術〕[Conventional technology]

従来、この種のデータ処理方式では、データの入出力は
そのファイルの作成状態、すなわちレコード長によって
決定され、−回の入出力はすべてレコード（レコード長
）単位で行なわれていた。Conventionally, in this type of data processing system, data input/output is determined by the creation state of the file, that is, the record length, and all input/outputs are performed in record (record length) units.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来の方式では、ユーザプログラムから実行で
きるデータの入出力は、レコード単位に限られているた

グラムでは繰り返し入出力処理を行なわなければならな
いので、処理速度が非常に遅くなる。In the conventional method described above, data input/output that can be executed from a user program is limited to record units, so user programs that process multiple records at once must perform repeated input/output processing. , processing speed becomes very slow.

〔課題を解決するための手段〕[Means to solve the problem]

A data processing method J is obtained.

〔実施例〕〔Example〕

Decide whether to perform the process on a record-by-record basis or on multiple records at once. −
When it is recognized that input/output is to be performed in units of records, conventional input/output processing 4 is performed. If it is recognized that multiple records are to be processed at once, it performs new input/output processing 5 and transfers control to the magnetic disk input/output interface 6.
Data is input/output to/from the external storage device 7.

In input/output method recognition processing 3, if the input/output data length and input/output buffer have been specified from the contents of control block 2, new input/output processing 5 is performed, and the input/output data length and input/output buffer are specified via the magnetic disk input/output interface 6. Returns the length of data to the specified buffer on the user program. If the input/output data length and human output buffer are not specified, conventional input/output processing 4 is performed and -record data is returned to the record area on the user program via the magnetic disk input/output interface.

This eliminates the need to repeatedly perform input/output processing.

また、複数レコードを一括して処理するため、データ処
理の高速化を計ることができる。Furthermore, since multiple records are processed at once, data processing speed can be increased.
