Patent Searching and Data


Title:
DIRECT SEARCH INPUT/OUTPUT SENTENCE PROCESSING SYSTEM FOR SEQUENTIAL ORGANIZATION FILE
Document Type and Number:
Japanese Patent JPS62276641
Kind Code:
A
Abstract:

PURPOSE: To apply I/O sentences based upon two searching methods to a sequential organization file by using I/O control information converted from direct search to sequential search I/O, and transferring data on the basis of the sequential search.

CONSTITUTION: A direct search output sentence WRITE (1, REC=99) I is executed to transfer the data of a variable I on a main storage device 5 previously defined by a user program 1 to a sequential organization file stored in an external storage device 4. Since a searching method included in an operating system (OS) 3 as a data transferring function is sequential search, an RTP 2 converts I/O control information in the main storage device 5 corresponding to the direct search I/O sentence into sequential search I/O information. On the basis of the converted information, the I/O control mechanism RTP 2 transfers data to a prescribed address by using the data transfer function based upon the sequential search included in the OS 3.
