Abstract

PURPOSE:To enable the titled controller to store respective record data inside a file in an optional address by providing controlling data inside the file. CONSTITUTION:A file 1 is composed of (n) record blocks; record data 1 of the file 1 are read, and the record data 1 are stored in a storage address 1. The next record reading necessary/unnecessary bit A of the record 1 is decided, if it is in a bit-on state, the next record data are read, and the data are stored in the said address. In the same way, operation is executed until the next block reading necessary/unnecessary bit A turns off. After the bit-off state, an executing necessary/unnecessary bit B after finishing loading is decided, and if it is in the bit- on state, an executing address 2 inside the record is changed to a computer executing address.

。Conventional file control requires control information such as a predetermined data storage address and the number of records to be read γ to be stored inside the AL computer. In addition, it was not possible to store file data at an arbitrary address with Recode 11 (. However, controlling a program with an overlay structure that is divided into a large number of functions has the disadvantage of being extremely complex.

To provide, [Summary of the Invention] V? of the present invention? The characteristics are: ■ At the beginning of each record 1 to 1 in the file, control data is stored at 1-nos, execution address after rope ink, information on whether or not to read the next record, 1 recode data, and checksum data. The purpose is to facilitate file management using structured files.
